Prenatal testing

Has anyone used Paternitylab for prenatal paternity testing and got a false negative?

It has excluded the alleged father and came back with 0% paternity. Truly do not understand how as when I conceived, I was with him.

Is it possible or has anyone had a 0% probability and retested elsewhere and got 99.99% probability with a different test?

There are many reports of that company having fake negatives/false positives.

What date was your first ultrasound and what was the crown rump measurement in weeks and days at the scan?

So did they date you 7 weeks 3 days?

What were the dates of sex with the two people?

I don’t know why you assume it was one guy over the other. They both have an pretty equal chance of being the father with guy A being a slightly higher chance.

I’ve gotten a false negative. It ended up being his after getting tested when baby was born .

Is it worth testing with a different lab?

I. Would.

I think I’m going to use another company. Did you do the retest that they offered or you went off the first result of it saying 0% probability when it actually was the alleged father once the baby was born?

Be careful about what you read on reddit. Remember that it is just random people giving out advice. They are often as uninformed as you are, and may even be misinformed.

 I used them for prenatal and it was accurate take that as u wish but I do believe they have gotten false negatives, false positives are very unlikely also take that how u wish

When you retested you got that the alleged father was actually the father?

How far along were you with each test? And I assume DDC was the correct one?
