Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like fatigue, weight changes, or unexplained bleeding. It’s also used for routine check-ups, especially if you’re at higher risk for HIV or thyroid issues.

What to Expect Before the Test

No special preparation is needed, but avoid heavy meals or caffeine before your blood draw. Fasted testing may be required for TSH if your doctor specifies it.

What the Results Mean

TSH results help diagnose thyroid disorders (like hypothyroidism or hyperthyroidism). HIV screening detects antibodies that may indicate past or current infection. Platelet counts assess bleeding risks or clotting disorders.

Common Conditions Linked to These Tests

High TSH may signal underactive thyroid; low TSH could indicate overactive thyroid. HIV screening is critical for early detection. Low platelet counts may signal bleeding disorders or other health concerns.

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.

Clinical significance: TSH levels guide thyroid hormone replacement or treatment. HIV antibodies confirm infection status, while platelet counts help manage bleeding risks or prevent complications from low counts.

Short name

HIV Screen + TSH + Platelet Check

Frequently asked questions

Will I need to fast before this test?
Sometimes, but your doctor will specify if fasting is required for the TSH portion. Otherwise, drink water and eat normally.
What if my HIV screening comes back positive?
A positive result means you may have HIV. Your doctor will guide next steps, including follow-up testing and treatment options.
Can I still donate blood if my platelet count is low?
Platelet counts below normal may temporarily disqualify you from blood donation. Check with your lab or donor center for specific guidelines.
