Included Markers
16 markersBehind the scenes, your body keeps a finely tuned balance, from your salt levels to your kidneys and your liver. A complete metabolic panel looks at these everyday processes and can give you insight into how your metabolism is doing right now.
This panel brings together sixteen blood values that together may say something about your fluid and salt balance, your kidney and liver function and your blood sugar. That can give you a little more grip on signals that are otherwise hard to read.
Why this test?
Vague complaints like tiredness, thirst or a bloated feeling can have many causes. A broad metabolic panel looks at a number of basic systems in your body at once, so you do not have to guess where to start.
This panel combines your electrolytes with markers for your kidneys, your liver and your blood sugar. Together they can give an impression of how your metabolism and fluid balance are doing at this moment.
Who is this test for?
This panel can be useful if you want a broader view of your metabolic health, for example with ongoing tiredness, frequent urination or thirst, or simply if you are curious about your values.
It can also be a handy starting point if you want to check in on your salt balance or your kidney and liver function. You do not need a referral from your GP.
What is tested?
This panel measures sixteen values in your blood, spread across your salt balance, kidneys, liver, blood sugar and proteins:
- Sodium: an electrolyte that helps regulate your fluid balance.
- Potassium: involved in nerve and muscle function, including your heartbeat.
- Chloride: an electrolyte that, together with sodium, helps set your fluid balance.
- Bicarbonate: involved in the acid-base (pH) balance of your blood.
- Calcium: important for bones, muscles and nerves.
- Creatinine: a waste product that can say something about your kidney function.
- eGFR (Estimated Glomerular Filtration Rate): a calculated estimate of how well your kidneys filter.
- Urea (BUN): a waste product from protein metabolism that your kidneys excrete.
- ALT (Alanine Aminotransferase): a liver enzyme that can reflect the condition of your liver.
- AST (Aspartate Aminotransferase): an enzyme found in the liver and muscles, among other places.
- ALP (Alkaline Phosphatase): an enzyme linked to the liver and bones.
- Bilirubin (Total): a breakdown product of red blood cells that your liver processes.
- Glucose (Fasting): your blood sugar after a period of fasting.
- HbA1c (Glycated Hemoglobin): gives an impression of your average blood sugar over the past weeks.
- Albumin: a protein made by your liver.
- Total Protein: the total amount of protein in your blood.
What can this test tell you?
The results can give you an impression of how different systems in your body are working together right now. Your electrolytes say something about your fluid and salt balance, while creatinine, eGFR and urea can paint a picture of your kidney function.
The liver enzymes and bilirubin may reflect how your liver is doing, and glucose and HbA1c offer insight into your blood sugar. Individual values say little on their own; it is the whole picture, combined with your situation, that can take on meaning.
How is the sample collected?
This test requires a blood draw at a certified laboratory. In the Netherlands you can choose from more than 750 sample points, so there is almost always a location near you.
After ordering, you pick a location and schedule a moment that suits you. The draw itself usually takes only a few minutes, and you do not need a referral.
When is this test useful?
A metabolic panel can be valuable at different moments, for example:
- when you feel persistently tired and want a broader view of your values
- with complaints like frequent thirst, frequent urination or a bloated feeling
- when you want to check in on your kidney and liver function
- when you like to follow your metabolic health periodically to stay informed
This panel does not replace a visit to your GP, but it can give you more context for what you feel.
What do the results mean?
Your result shows each value with a corresponding reference range and a short explanation. What counts as usual can vary by laboratory and from person to person.
A value that falls outside the range does not automatically mean something is wrong; it can also relate to your diet, fluid intake or the timing of the draw. The doctor helps you place your values in the right context.
Preparation
For this panel it is usually advisable to have your blood drawn while fasting, because your glucose is affected by food. That generally means not eating for 8 to 12 hours beforehand and drinking only water.
You will receive the exact instructions with your order, so you arrive well prepared. Scheduling your draw in the morning often makes fasting easiest to fit in.
What happens after the results?
Your result is usually available online within a few working days. Each value is shown clearly with a reference range and an explanation, so you understand what you see.
Every blood test result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.

Learn moreCreatinine is a waste product generated by normal muscle metabolism that is filtered out of the blood by the kidneys. It is widely regarded as the gold standard marker for evaluating kidney function, as consistent production makes it a reliable indicator of filtration efficiency.
Learn moreeGFR (estimated glomerular filtration rate) is a calculated measure of how effectively your kidneys filter waste from the blood. It is the gold standard for diagnosing and staging chronic kidney disease and is derived from blood creatinine or cystatin C levels along with demographic factors.
Learn moreFasting glucose measures the level of sugar (glucose) in your blood after an overnight fast. It is one of the primary tests used to screen for and monitor diabetes and pre-diabetes.
Learn moreBicarbonate is an electrolyte that helps maintain the body's acid-base balance. It acts as a buffer in the blood, neutralising excess acids and helping to keep your pH within a healthy range.
Learn moreChloride is an essential electrolyte that helps maintain fluid balance, blood pressure, and the body's acid-base equilibrium. It works closely with sodium and potassium to regulate these vital functions.
Learn moreSodium is a vital electrolyte that regulates fluid balance, blood pressure, and nerve and muscle function. It is the primary cation in extracellular fluid and is closely regulated by the kidneys.
Learn morePotassium is an essential electrolyte and mineral that helps regulate heartbeat, muscle contractions, nerve signals, and fluid balance. It is one of the most important minerals for cardiovascular health.
Learn moreAlbumin is the most abundant protein in the blood, produced by the liver. It maintains fluid balance, transports hormones and nutrients, and serves as an indicator of liver and kidney function.
Learn moreTotal protein measures the combined amount of albumin and globulins in your blood. These proteins play essential roles in maintaining fluid balance, fighting infections, transporting substances, and supporting tissue repair.
Learn moreHbA1c (Glycated Hemoglobin)
MetabolicHbA1c (glycated haemoglobin) reflects your average blood sugar levels over the past 2-3 months. It is the gold standard for long-term blood sugar monitoring and diabetes management.
HbA1c provides a long-term view of blood sugar control, unlike fasting glucose which reflects a single point in time. It is essential for diabetes diagnosis and management. Consult your healthcare provider.
ALT (Alanine Aminotransferase)
LiverALT (alanine aminotransferase) is a liver enzyme that serves as a key indicator of liver health. Elevated levels may suggest liver cell damage and can be associated with various liver conditions.
ALT levels provide important insight into liver function. Elevated levels may indicate conditions such as hepatitis, fatty liver disease, or medication-related liver damage. Early detection of elevated ALT can help identify liver problems before symptoms develop, allowing for timely intervention and lifestyle modifications.
Calcium
MineralsCalcium is the most abundant mineral in the body, essential for strong bones and teeth, muscle contraction, nerve signalling, and blood clotting. Most calcium is stored in bones and teeth, with a small amount circulating in the blood.
Calcium balance is critical for bone health, heart function, and muscle contraction. Abnormal levels may be associated with bone disorders, parathyroid conditions, or kidney problems. Consult your healthcare provider for personalised advice.
ALP (Alkaline Phosphatase)
LiverAlkaline Phosphatase (ALP) is an enzyme found in the liver, bones, kidneys, and digestive system. ALP levels can help evaluate liver health, bone disorders, and bile duct function.
ALP is a useful screening marker for liver and bone conditions. Elevated levels may indicate bile duct obstruction, liver disease, or bone disorders. Consult your healthcare provider for interpretation.
AST (Aspartate Aminotransferase)
LiverAST (aspartate aminotransferase) is an enzyme found in the liver, heart, and muscle cells. Elevated levels may indicate liver damage, but because AST is present in multiple tissues, results are best interpreted alongside other liver markers such as ALT.
AST levels provide important information about the health of your liver, heart, and muscles. Elevated levels may be associated with conditions such as hepatitis, cirrhosis, heart attack, or muscle injury. When evaluated alongside ALT, the AST:ALT ratio can help your healthcare provider identify the underlying cause of liver enzyme elevation. An AST:ALT ratio greater than 2:1, for instance, may suggest alcohol-related liver damage.
Bilirubin (Total)
LiverTotal bilirubin measures the combined amount of direct and indirect bilirubin in your blood. Bilirubin is a waste product formed during the normal breakdown of red blood cells, and elevated levels may indicate liver disease, bile duct problems, or increased red blood cell destruction.
Total bilirubin is a fundamental marker for assessing liver function and diagnosing the cause of jaundice. By comparing total bilirubin with direct bilirubin, healthcare providers can determine whether elevation is due to liver disease, bile duct obstruction, or haemolysis. Mild elevations may occur in common and generally harmless conditions such as Gilbert syndrome, which affects approximately 5-10% of the population. However, significant elevations warrant further investigation to rule out serious underlying conditions.
Urea (BUN)
KidneyBUN (blood urea nitrogen) measures the amount of urea nitrogen in your blood, a waste product formed when the body breaks down protein. It is primarily used to evaluate kidney function and can be influenced by diet, hydration status, and liver health.
BUN is a valuable marker for assessing how effectively your kidneys are filtering waste from your blood. Elevated levels may indicate that the kidneys are not functioning optimally, which can be associated with dehydration, kidney disease, or other underlying conditions. Monitoring BUN alongside other kidney markers such as creatinine and eGFR provides a more comprehensive picture of renal health and helps detect potential problems early.
Creatinine
KidneyCreatinine is a waste product generated by normal muscle metabolism that is filtered out of the blood by the kidneys. It is widely regarded as the gold standard marker for evaluating kidney function, as consistent production makes it a reliable indicator of filtration efficiency.
Creatinine is central to assessing kidney health. It is used to calculate the estimated glomerular filtration rate (eGFR), which is the primary measure for staging chronic kidney disease. Early detection of rising creatinine levels can prompt timely intervention, helping to slow the progression of kidney damage. Monitoring creatinine is also important for adjusting medication dosages, as many drugs are cleared by the kidneys.
eGFR (Estimated Glomerular Filtration Rate)
KidneyeGFR (estimated glomerular filtration rate) is a calculated measure of how effectively your kidneys filter waste from the blood. It is the gold standard for diagnosing and staging chronic kidney disease and is derived from blood creatinine or cystatin C levels along with demographic factors.
eGFR is the most important single measure for assessing overall kidney function. It is used internationally to diagnose chronic kidney disease, determine its stage, and guide treatment decisions. Regular eGFR monitoring allows early detection of kidney function decline, often before symptoms appear. This is critical because early intervention can significantly slow the progression of kidney disease and reduce the risk of complications such as cardiovascular disease.
Glucose (Fasting)
MetabolicFasting glucose measures the level of sugar (glucose) in your blood after an overnight fast. It is one of the primary tests used to screen for and monitor diabetes and pre-diabetes.
Fasting glucose is a cornerstone of metabolic health assessment. Elevated levels may indicate pre-diabetes or diabetes, while very low levels can also be clinically significant. Consult your healthcare provider for interpretation.
Bicarbonate
MineralsBicarbonate is an electrolyte that helps maintain the body's acid-base balance. It acts as a buffer in the blood, neutralising excess acids and helping to keep your pH within a healthy range.
Proper bicarbonate levels are essential for maintaining blood pH. Imbalances may indicate respiratory or metabolic conditions and can affect organ function. Consult your healthcare provider for interpretation of your results.
Chloride
MineralsChloride is an essential electrolyte that helps maintain fluid balance, blood pressure, and the body's acid-base equilibrium. It works closely with sodium and potassium to regulate these vital functions.
Chloride imbalances can indicate dehydration, kidney disease, or acid-base disturbances. Maintaining proper chloride levels is important for overall metabolic health. Consult your healthcare provider for result interpretation.
Sodium
MineralsSodium is a vital electrolyte that regulates fluid balance, blood pressure, and nerve and muscle function. It is the primary cation in extracellular fluid and is closely regulated by the kidneys.
Sodium balance is essential for proper nerve transmission, muscle contraction, and blood pressure regulation. Significant imbalances can affect brain function and require medical attention. Consult your healthcare provider for guidance.
Potassium
MineralsPotassium is an essential electrolyte and mineral that helps regulate heartbeat, muscle contractions, nerve signals, and fluid balance. It is one of the most important minerals for cardiovascular health.
Potassium is critical for maintaining heart rhythm, blood pressure regulation, and proper muscle function. Both low and high levels can be dangerous and may require medical attention. Consult your healthcare provider for interpretation.
Albumin
LiverAlbumin is the most abundant protein in the blood, produced by the liver. It maintains fluid balance, transports hormones and nutrients, and serves as an indicator of liver and kidney function.
Albumin is important for maintaining blood volume, transporting substances, and reflecting overall health status. Low levels may indicate liver disease, kidney disease, or malnutrition. Consult your healthcare provider.
Total Protein
OtherTotal protein measures the combined amount of albumin and globulins in your blood. These proteins play essential roles in maintaining fluid balance, fighting infections, transporting substances, and supporting tissue repair.
Total protein levels provide a general overview of your nutritional status, liver function, kidney function, and immune system activity. Abnormal levels may prompt your healthcare provider to investigate specific protein fractions further.
