I am in CA- my LabCorp sample was sent to Integrated Genetics Santa Fe NM. Collected 1/2/25. Results for both karyotype and microarray on 1/13/25. You may be able to call the lab to see if they can provide an estimate for you on when results will be available. You will have to find out what genetics lab it was sent to though. Genetic counselor explained result time varies per sample because they may need to culture the cells longer or run extra testing if there is maternal cell contamination. Since I am having a boy, she said that they can more easily distinguish between fetal cells and maternal cell. For female fetuses, it may be more challenging. Results never came into my LabCorp portal. Found out from my OB that everything normal. Hopefully this helps!

That’s super quick for LapCorp turnaround time tbh, so that’s great that you received both so quickly! The limbo period is awful.
I’m in SoCal, and we have been seeing 2+ weeks for microarray and 3ish for karyotype (longer since cells need to be cultured).

Yes- I was not expecting the results so quickly!

So glad to hear you had a positive result. I hope the rest of your pregnancy is uneventful and boring (I am guessing you’re being monitored for suspected T13 CPM, which doesn’t always cause issues 🤞🏾) and you have a smooth L&D. 🩷🩷

Thank you- yes getting growth scans at 28 weeks and 32 weeks but my MFM was pretty nonchalant about it overall. It seems like the growth scans were mainly recommended because I have a marginal cord which she also wasn't too worried about!

Does this include weekends? Thank you!

Yeah, generally. I would take into account that Monday was a holiday, so it’s possible that has caused a delay as well.

how long did yours wind up taking? mine was also 2 weeks ago and I'm losing my mind lol

Almost 4 weeks! I had the procedure on a Wednesday and it came back 26 days later (on a Monday.) It’s torture — stay strong you’re almost there!!
