New 48-Hour Early Gender DNA Blood Test
The Fastest Early Gender Blood Test
Starlight can now offer an even faster service with accurate blood test results (99.9%) confirming gender from 6 weeks into pregnancy in 24-48 hours.
In addition to offering gender determination ultrasound scans from 13 weeks, we offer the SneakPeek Clinical Early Gender Blood Test with results in 4-7 working days because samples are sent to America.
The Starlight Express blood test is available for £150 or alongside an early pregnancy scan for £225. An early pregnancy scan can confirm a pregnancy is at least six weeks as tests performed earlier than that can may generate inaccurate or inconclusive results.
The same science and technology determines the gender via a blood test but because we now have access to a UK lab to provide the results, it means a much faster turnaround.
When a pregnancy has been confirmed as at least six weeks via ultrasound as opposed to LMP, there has not been a single incorrect test result.
By around 6-8 weeks of pregnancy there is usually sufficient circulating cell-free DNA (ccfDNA) in the blood to detect if Y-chromosome DNA is present.
The genetic difference between the sexes is that males have a Y-chromosome and females do not.
If no male Y-chromosome DNA is identified then the baby is reported as a girl.
For samples received before 10am, the results should be available the same day so it is dependent on the postal service delivering the sample. They are sent via a 24-hour tracked service so there is a good chance of next-day results but otherwise it will be 48 hours later.
The blood test is available for £150 or with an early pregnancy scan for £225. An early pregnancy scan can confirm a pregnancy is at least six weeks as tests performed earlier than that can may generate inaccurate or inconclusive results.
A simple blood draw is all that is required and the sample is sent by 24 hour tracked Royal Mail postage to a UK lab where it is tested.
For samples received by 10am, the results are emailed the same day. After that time, the results will usually be available the following day.
It is true that the later in pregnancy (so 8 weeks compared to 6 weeks) there will be more fetal DNA so it is likely to be more accurate and reliable however it is fine to book in from 6 weeks and this is why we recommend the early scan and blood test to ensure the pregnancy is definitely at least 6 weeks.
Please note, BMI and/or weight can affect how much fetal DNA is in a pregnant lady. If a lady weighs over 85kg then it is recommended to wait until at least 10 weeks pregnant before doing the test as there is a slightly higher chance that there will not be enough male DNA in her blood to be detected before then.
This service is available at both Starlight Ultrasound clinic locations in Bury and Hale and can be booked online 24/7, in person at either clinic or over the phone.
