The Accuracy Of HIV Testing Using The ELFA Method?
. I tested HIV after 4 months of doing risky with the elfa method. And the results are nonreactive. Is the elfa method accurate?
Hello Ms. Iwan 23 Thank you for consulting us on HealthReplies.com. Basically, ELFA (Enzyme Linked Fluorescent Assay) is the latest type of examination that is perfected from previous serological tests, namely ELISA (Enzyme Linked Immunosorbent Assay). The purpose of the examination is the same as the previous conventional method (ELISA) which is to detect the presence of antibodies in the sample taken. It's just the difference between the two is the reagent or substrate used.
The accuracy is arguably the same or even better than ELISA. And can detect about 95% of infections at 28 days, and more accurately approach 99.9% of infections at 90 days. The ELFA method has a high enough sensitivity and specificity to diagnose HIV. So if the result is non-reactive, then that means you are not infected with HIV. It's just that this doesn't indicate that you are immune to the HIV virus or other sexually transmitted viruses, so you need to be careful not to have free sexual relations. Thus we can convey, hopefully our information can be useful for you. thanks.
