I did mutual masturbation with boy. Hiv status unknown. Their was no anal or oral sex. But we touched each other maybe there was precum which got in my glans. So I got extremely worried and at 90th day I took 4th gen hiv test (eclia) method which an index value is 0.337 (nonreactive. Is it conclusive. Do I need any more test?

No need for further testing for hiv.

I am sorry to hear about your concern but will be happy to assist you. For anti-hiv 1 and 2, rdt showed 100% accuracy and eclia showed 99% accuracy. For anti-hcv, eclia by ecivitros showed better sensitivity than corresponding rdt (sensitivity100% versus sensitivity 66.7% respectively). Let's connect over a call so that we can discuss your concern in details and make a suitable treatment plan for you.
