Thyroid Complete

The thyroid gland influences metabolism, energy, mood, and reproductive health. Symptoms of thyroid imbalance can be subtle and overlap with many other conditions, making blood testing a commonly used approach. This panel goes beyond basic thyroid screening by including antibody markers, which may help identify autoimmune patterns.

This test may be relevant for women who:

• Experience symptoms such as fatigue, weight changes, or mood fluctuations
• Have a family history of thyroid conditions
• Want to check for autoimmune thyroid markers
• Are experiencing fertility-related concerns, as thyroid function can influence reproductive health

This panel measures five markers:

• TSH (Thyroid Stimulating Hormone): produced by the pituitary gland to regulate thyroid activity; often the first marker checked in thyroid screening
• Free T4: the unbound form of thyroxine, the main hormone produced by the thyroid
• Free T3: the unbound form of triiodothyronine, the more active thyroid hormone
• TPO Antibodies (Anti-TPO): antibodies directed against thyroid peroxidase; elevated levels may be associated with autoimmune thyroid conditions such as Hashimoto's thyroiditis
• Thyroglobulin Antibodies (Anti-Tg): antibodies directed against thyroglobulin; may also be associated with autoimmune thyroid involvement

TSH, Free T4, and Free T3 together provide a picture of how the thyroid is functioning. An elevated TSH with low Free T4 may suggest underactive thyroid function, while a suppressed TSH with elevated Free T4 or T3 may suggest overactivity. The antibody markers add another layer: elevated TPO or Tg antibodies may indicate an autoimmune component, which can be relevant for understanding the underlying cause and for long-term monitoring.

The test requires a blood draw at a certified sample point (afnamepunt). There are over 750 locations across the Netherlands. After placing your order, you can select a convenient location and schedule your visit.

This test may be considered when:

• You experience persistent fatigue, unexplained weight changes, or sensitivity to cold or heat
• You have a family history of thyroid or autoimmune conditions
• You want a more thorough thyroid assessment beyond TSH alone
• Thyroid involvement is being considered in the context of fertility or menstrual irregularity

Each marker is presented with your value and the reference range. Abnormal TSH alongside abnormal Free T4 or T3 may suggest a thyroid imbalance. Elevated antibody levels do not always mean active disease, but they may indicate a predisposition to autoimmune thyroid conditions. Results should be interpreted by a healthcare provider who can consider them alongside your symptoms and medical history.

No specific preparation is needed. No fasting is required. If you take thyroid medication, discuss timing with your healthcare provider, as some providers prefer testing before the morning dose.

Your results are typically available within a few working days. Each marker is shown with your value, the reference range, and an explanation. These results can serve as a basis for discussion with your healthcare provider about whether further evaluation or follow-up may be appropriate.
