A member asked:

I had the informaseq test done. it came back negative for all 3 syndromes. what does that actually means? how accurate and sensitive is this test?

Negative predictive: Value of all 3 tests is 99.9%. This means only 1 of 1000 or fewer will actually have the syndromes if the test is negative. As accurate as medical testing gets. Thanks for trusting HealthTap!

Ive had three HSV IGG CLIA blood tests done (4, 6, & 7 months post exposure). HSV 2 is negative but HSV 1 is inconclusive. What do three equivocal HSV 1 (.90) results mean? Should I consider this negative or positive? Two years ago, it was negative?
