Frequently Asked Questions
What does CD4 count measure?
CD4 count measures the number of helper T lymphocytes in your blood, which are critical white blood cells that coordinate the immune response against infections.
Is fasting required for CD4 test?
No fasting is required. The test can be performed at any time of day without dietary restrictions.
Why is CD4 count important for HIV patients?
CD4 count is the primary marker used to monitor immune system damage in HIV patients. A declining count indicates disease progression, while rising counts reflect effective antiretroviral therapy.
What is a normal CD4 count range?
A normal CD4 count ranges from 500 to 1,500 cells/μL in healthy adults. Counts below 200 cells/μL indicate severe immunosuppression and high risk for opportunistic infections.
How long does it take to get CD4 results?
Results are typically available within 24 to 48 hours. Verified PDF reports can be accessed via www.drpatholab.in or WhatsApp/Email.
Can stress or illness affect CD4 results?
Yes, acute infections, stress, and certain medications can temporarily lower CD4 counts. Your doctor may recommend repeat testing for accurate baseline assessment.
