Thyroid-stimulating hormone (TSH) with HIV-related screening/confirmation panel (serum/plasma mass concentration)
This test measures thyroid-stimulating hormone (TSH) levels in your blood, often performed as part of an HIV-related evaluation to assess thyroid function while monitoring for HIV-related conditions.
["TSH helps regulate your thyroid hormones and may be checked if you have symptoms or risk factors related to HIV or thyroid issues."]

What This Test Measures
TSH is a hormone produced by your pituitary gland that signals your thyroid to produce thyroid hormones (like thyroxine). This test specifically evaluates TSH levels in serum or plasma, which can indicate whether your thyroid is functioning normally or if there may be an underlying issue, especially in the context of HIV-related health monitoring.
Why It’s Done in HIV Care
In HIV care, TSH testing may be part of routine or targeted screening to detect thyroid dysfunction, which can occur due to HIV infection, medications, or other health factors. It helps healthcare providers monitor thyroid health alongside HIV treatment and overall well-being.
How the Test Works
A blood sample is drawn and analyzed using an immunoassay method to measure TSH concentration. This process detects the hormone’s presence and concentration in your bloodstream, providing critical data for assessment.
What to Expect Before the Test
No special preparation is usually needed, but you may be asked to fast for 8–12 hours before the test if instructed by your provider. Wear comfortable clothing and plan to stay near the testing site for the blood draw.
Reference range
Adult: 0.4-4.0 mIU/LN/A
Take your thyroid medication after the blood draw if applicable. No fasting required.
