I was able to book an in-person appointment on the same day and then add an additional test when I arrived. The phlebotomist was kind and efficient.

I'd like to share my experience. The nurse was very kind; I didn't feel the needle when she drew my blood. The appointments were on time, and the results were quick.
Thank you

It was all extremely speedy and efficient. I ended up going to the clinic because it was difficult for me to collect enough blood from my fingertips due to Raynauds. Going to the clinic was for me a lot simpler than doing it myself and next time I will just pop into the clinic. But yes, I can't fault them, an excellent service and they provide loads of useful info with the results too.

Extremely disappointing
Extremely disappointing. I was very careful to look at turnaround time on their website (for NIPT3 it says 4-6 working days) and made sure to take my doctor appointment 8 working days after they received my sample. 6 working days after I still had not received my results, no news from One Day tests. I emailed them to then receive the below answer:
“ Due to the analyser being down at the referral lab, the estimated turnaround time has been slightly longer.”
I had to cancel my doctor appointment which I will only get again in 2 weeks!
If I hadn’t emailed I would have waited and gone to my doctor with no test results !
You CANNOT TRUST them on turnaround time so if you need tests done in a certain time for later appointments go to another company!

Hello,
we perform thousands of tests on time and accurately. NIPT takes time and specialised laboratory, which has experienced an issue and the results were slightly delayed, apologies.
We wish you all the best
