I’m sure a hundred stories are worth below a mediocre research report, but in the absence of an effective browse I realized I might place an anecdote to your comments. We acquired an excellent 93% PPV confident to possess T21 towards a Claritest tests. This new genetics specialist we had been referred to advised us the newest PPV is “in fact more than 99%” centered on an inside Kaiser data (she indeed did not recognize to cherry-picking data up to I insisted into the enjoying my personal test results).
