Why This Test Is Done

Your healthcare provider may order this test if you have symptoms of thyroid issues (like fatigue or weight changes) or if HIV screening is part of routine care. It may also be done during follow-up for HIV-related conditions.

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample, usually from a vein in your arm, by a phlebotomist.

What the Test Results Mean

TSH measures how well your thyroid gland is working. HIV-related markers help detect or monitor HIV infection. Results may be compared to general reference ranges for TSH and specific HIV antibody thresholds.

Common Causes for Testing

This test could be ordered for thyroid disorders (hypo/hyperthyroidism), HIV screening, or monitoring HIV-related thyroid complications.

Reference range

Adult: 0.4-4.0 mIU/LN/A

Specimen: serum

Take your thyroid medication after the blood draw if applicable. No fasting required.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

HIV can affect thyroid function, and thyroid issues may worsen HIV-related symptoms. Early detection helps manage both conditions better.
This test helps identify thyroid hormone imbalances and HIV exposure markers, guiding treatment decisions.
What does a high or low TSH level mean?
A high TSH may indicate hypothyroidism (underactive thyroid), while a low TSH may suggest hyperthyroidism (overactive thyroid). HIV markers help determine if HIV antibodies are present.
How long does it take to get results?
Results are typically available within 1–3 business days, depending on lab processing times.
