IFA vs. Western Blot
Dec 29, 2008

Hi Robert -

I was looking into the Home Access HIV kit and I believe they perform an ELISA and then the IFA, not the Western Blot. I was wondering if you knew the differences and if it is just better to go to a doctor and get the standard ELISA with confirmatory WB. I fear using the home kit and getting an inaccurate result. Thank you.

Response from Dr. Frascino

Hello,

IFA (immunofluorescence assays) are as accurate as WBs (Western Blots) when used to confirm a positive ELISA. Your fears are unwarranted. The Home Access HIV test kits are extremely accurate. However, if you would prefer an in-office ELISA and confirmatory WB, that option is certainly available as well.

Dr. Bob
