Question 1

What is the window period for MERISCREEN™ HIV 1–2 WB?

Accepted Answer

The window period depends on antibody development. IgM antibodies typically become detectable around 3 weeks or later after viral replication begins. Testing during the window period may yield non-reactive results despite infection.

Question 2

What should be done if the test result is reactive?

Accepted Answer

A reactive result must be confirmed according to national testing algorithms. As per NACO guidelines, reactive samples should be tested using three different assays before reporting, following the prescribed HIV testing strategy for asymptomatic individuals.

Question 3

How can errors be avoided while performing the test?

Accepted Answer

Errors can be minimized by using the recommended sample volume with the dropper and adding only the specified number of buffer drops using only the buffer supplied with the kit. The test device should be used immediately after opening and handled as per instructions.

Question 4

What if a test band appears after the recommended reading time?

Accepted Answer

Any result observed after the specified reading time is considered invalid. Interpretation must strictly follow the timing mentioned in the Instructions for Use to ensure reliable and accurate results.
