Platelets: what your blood count may mean

Platelet monitoring is particularly relevant for women, as changes in platelet levels can be associated with menstrual health, pregnancy, and hormonal fluctuations. Understanding your platelet count empowers you to stay informed about your blood health and take proactive steps.

Reference Ranges

Female
10^9/l
Low 150 Normal 400 High

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

What It Measures

This test measures the total number of platelets (thrombocytes) per volume of blood. Platelets are produced in the bone marrow and play a critical role in hemostasis by forming clots at the site of blood vessel damage to prevent excessive bleeding.

Why It Matters

Abnormal platelet counts can have significant health implications. Low platelet counts (thrombocytopenia) may increase the risk of bleeding, while high counts (thrombocytosis) can be associated with an increased risk of blood clots. Monitoring platelet levels helps detect blood disorders and guides treatment decisions.

When to Test

Platelet counts are included in a complete blood count (CBC) and may be ordered during routine health screening, before surgical procedures, when unusual bleeding or bruising occurs, or to monitor conditions affecting platelet production.

Symptoms

Low Levels

Easy bruising, prolonged bleeding from cuts, frequent nosebleeds, bleeding gums, blood in urine or stool, heavy menstrual periods, petechiae (small red or purple spots on skin).

High Levels

Headaches, dizziness, chest pain, weakness, tingling in hands and feet, and in some cases, paradoxically increased bleeding risk.

Lifestyle Tips

Maintain a balanced diet with adequate folate, vitamin B12, and iron to support platelet production. Stay hydrated and avoid excessive alcohol consumption. If you have a low platelet count, take precautions to avoid injury and discuss any medication use with your healthcare provider.

Frequently Asked Questions

What can cause a low platelet count?
Low platelet counts can be associated with viral infections, autoimmune conditions, certain medications, liver disease, or bone marrow disorders. In some cases, platelet destruction occurs faster than production. Your healthcare provider will investigate the underlying cause.
Can certain medications affect platelet counts?
Yes, some medications including aspirin, blood thinners, certain antibiotics, and chemotherapy drugs can affect platelet counts. Always inform your healthcare provider about all medications you are taking before blood testing.
