Why This Test Is Done

Your doctor may order this test if you have symptoms of thyroid problems (like fatigue, weight changes, or mood swings) or if HIV screening is recommended (e.g., pre-exposure prophylaxis, sexually active without protection, or post-exposure evaluation). It may also be part of routine check-ups for certain groups.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into your arm or vein to draw blood. Tell your healthcare provider if you’re on blood-thinning medication or have a history of bleeding issues.

What the Test Results Mean

TSH levels help diagnose thyroid disorders (e.g., hypothyroidism or hyperthyroidism). HIV antibody confirmation confirms or rules out HIV infection. Your doctor will interpret results in the context of your symptoms and medical history.

Possible Results and Next Steps

If TSH is abnormal, further thyroid function tests (like free T4 or antibodies) may be needed. If HIV antibodies are detected, additional testing (e.g., viral load) will follow to confirm or rule out HIV.

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.

Frequently asked questions

What does an abnormal TSH level indicate?
High TSH often means hypothyroidism (underactive thyroid), while low TSH may suggest hyperthyroidism (overactive thyroid). HIV antibody confirmation is critical for early treatment and management.
How long does it take to get results?
Results for TSH and HIV screening are typically available within 1–3 business days, depending on lab processing times.
Can I eat or drink before this test?
Yes, you can eat and drink normally. Avoid alcohol 24 hours before the test if your doctor recommends it, as it may affect blood chemistry.
