How Long Does QNatal Test Take? A Mother’s Insight ?️
When it comes to prenatal testing, the question on every expectant mother’s mind is, “how long does qnatal results take?” Well, I’ve been through this journey a few times, and I can share that the QNatal test, a non-invasive prenatal screening, generally has a turnaround time of 7-10 days. This means, from the moment you have your blood drawn, you can expect to receive your results within this timeframe, giving you insights into any chromosomal abnormalities your baby might have.
A Closer Look at the QNatal Test Procedure
The QNatal test, officially known as the QNatal Advanced Noninvasive Prenatal Screen, is a marvel of modern medicine, designed to screen for fetal chromosomal abnormalities. Developed and performed exclusively by Quest Diagnostics, it’s a test that’s become a staple in prenatal care, screening for conditions like trisomy 21, 18, and 13, and even determining the fetal sex.
Blood Draw and Initial Steps
The process starts with a simple blood draw, which can be done as early as 10 weeks into pregnancy. This blood draw is quite straightforward and takes about 10 minutes. Once the blood is drawn, it’s sent to a laboratory for processing, which typically takes 1-2 days. The lab extracts and amplifies the cell-free DNA (cfDNA) from the blood, allowing it to be analyzed.
Analyzing the Results
After the sample processing, the laboratory delves into results analysis, which takes about 3-4 days. They scrutinize the cfDNA for the presence of common chromosomal abnormalities. It’s a meticulous process, ensuring the accuracy of the results you’ll receive.
Receiving the Results
Finally, after the analysis, the total turnaround time sums up to 7-10 days. This means, within a week or two, you’ll have the results in your hands, allowing you to make informed decisions about your pregnancy.
The Importance of Timing in the QNatal Test ?
How Long Does Qnatal Results Take?
The timing of the QNatal Advanced test is crucial. It’s recommended not to conduct the test earlier than 10 weeks into pregnancy. Doing so may lead to significantly inaccurate results.

If there’s a specific genetic disorder you’re concerned about, discuss it with your healthcare provider. They can guide you on the appropriate tests to take.
Are NIPTs mandatory during pregnancy? ?♀️
No, NIPTs are not mandatory during pregnancy. They are offered as an option to provide additional information about the baby’s health. It’s entirely up to you whether to undergo this screening. Some parents choose to have it for peace of mind, while others opt not to. It’s a personal decision, and it’s important to consider your values, preferences, and any potential implications of the test results when deciding.
Can NIPTs determine the sex of the baby? ?
Yes, NIPTs can indeed determine the sex of the baby. They analyze the cell-free DNA in the mother’s blood, which includes the baby’s genetic information. This allows the test to identify the presence of Y chromosomes, which would indicate a male baby. If no Y chromosomes are detected, it suggests a female baby. However, if knowing the sex of the baby is not desired, you can request not to have this information disclosed.
How do I interpret the results of an NIPT? ?
Interpreting the results of an NIPT can be a bit overwhelming. Typically, the results will indicate whether the baby is at low or high risk for specific chromosomal abnormalities. A low-risk result means that it’s unlikely the baby has the conditions screened for. A high-risk result doesn’t mean the baby has a condition; it just indicates an increased likelihood. It’s crucial to discuss the results with your healthcare provider or a genetic counselor to understand them fully and decide on any further steps or testing if needed.
How reliable are NIPTs for twin pregnancies? ??
NIPTs can be used for twin pregnancies, but the reliability might be slightly reduced compared to singleton pregnancies. The test analyzes cell-free DNA from the placenta in the mother’s bloodstream, and with twins, there’s DNA from two placentas. This can complicate the analysis. However, advancements in technology are continually improving the accuracy and reliability of NIPTs for twin pregnancies. Always discuss the reliability and any concerns with your healthcare provider.
Do insurance plans typically cover the cost of NIPTs? ?
Many insurance plans do cover the cost of NIPTs, especially if you’re over 35 or have a higher risk of chromosomal abnormalities. However, coverage can vary widely between different insurance providers and plans. It’s always best to check with your insurance company beforehand to understand your coverage and any out-of-pocket costs you might incur.
Should I opt for NIPT or stick to standard prenatal screening? ?
Choosing between NIPT and standard prenatal screening is a personal decision. NIPTs offer a higher level of accuracy and can be done earlier in pregnancy compared to some standard screenings. They are noninvasive and pose no risk to the baby. However, standard screenings are also valuable and have been used for many years to assess the risk of chromosomal abnormalities. Discuss your options, preferences, and any specific concerns with your healthcare provider to make an informed decision.
Can I have an NIPT if I have a BMI over 30? ?️♀️
Yes, you can have an NIPT if you have a BMI over 30, but it’s important to know that a higher BMI can increase the chance of not getting a result from the test. This is because the amount of cell-free fetal DNA in the blood may be lower in individuals with a higher BMI. If the first test doesn’t yield a result, it can often be repeated, and a result may be obtained in a subsequent attempt.
Is counseling recommended before and after NIPT? ?️
Counseling is indeed recommended both before and after undergoing an NIPT. Before the test, counseling can help you understand the test’s benefits, limitations, and potential outcomes. It can assist you in making an informed decision about whether to proceed with the test.
