How long do traces of Y chromosome stay?
I know with all of these new blood tests that can detect gender there is a chance of a false reading if you have had a past boy pregnancy and there is any Y to detect still in your system. Does anyone know how long that would stick around for?

I'm not sure anyone knows really. All the tests are pretty new. This is from the Pink or Blue website talking about their blood DNA test-
Factors which could affect the accuracy of Pink or Blue® which cannot be controlled:
Having naturally low levels of fetal DNA: studies have determined that up to 2.8% of women have naturally low levels of fetal DNA. While Pink or Blue® is much more sensitive than the methods used in those studies, there may still women whose levels of fetal DNA are too low even for our test to detect. This is a difficult statistic to measure but we anticipate it is less than 2%.
Vanishing Twin: some pregnancies begin with more two fetuses but very early in the pregnancy, one of the fetuses terminates. In many cases, this occurs without the woman’s knowledge. If the “vanishing twin” is male and the remaining fetus is female, the results of Pink or Blue® may be incorrect.
Previous male pregnancy: in very rare cases, fetal cells may remain in the mother’s body several years after birth. Our technology can detect some of this DNA as a form of contamination, however, there may be cases where the accuracy of the test may be affected by this rare occurrence.
Having a bone marrow transplant from a male donor, blood transfusions, miscarriages or abortions: our technology can detect DNA from previous male pregnancies or from male blood/marrow donors as contamination in most cases. However, there may be instances where the accuracy of our test is affected by any of these conditions.Mom to

Fragments of fetal DNA will linger in your blood****** for the rest of your life from every baby and miscarriage you've ever had. HOWEVER, the maternal blood tests they are doing now are for cell-free fetal DNA, and that leaves your body quickly after birth or miscarriage. According to wikipedia, 2 hours after birth, the cffDNA can no longer be detected.

Incorrect information
Wikipedia is not a credible source of information.
IVF studies and NCBI medical studies to name a *few by highly regarded Physicians and IVF specialists have proven that cellular fetal DNA/cffDNA clearly can be present in blood long term.
Miscarriage or not. This is why DNA tests like sneak peak and my Doctor state you cannot test if you have had a miscarriage in the past Three months minimum.
People can properly research these studies, One is : Fetal cellular microchimerism in pregnancy and miscarriage/www.ncbi.nim.nih.govLast edited by Liz5757; January 4th, 2018 at 11:42 AM.
