Understanding QNatal Advanced: A Comprehensive Guide to Scheduling an Appointment

Quest Diagnostics' QNatal Advanced is a laboratory-developed test that has been validated and developed in accordance with the Clinical Laboratory Improvements Amendments of 1988 (CLIA). As a screening test, it is essential to understand how this test works and what you can expect during your appointment.

How the Test Works

The QNatal Advanced is a cell-free DNA test that screens for increased risk of certain fetal chromosomal abnormalities. These abnormalities may cause birth defects, including Trisomy 21 (Down Syndrome), Trisomy 18, Trisomy 13, and certain sex chromosome abnormalities such as 45,X, 47,XXY, 47,XXX, and 47,XYY.

Appointment Schedule

To schedule an appointment for the QNatal Advanced test, you can contact Quest Diagnostics at 1.866.436.3463. It is essential to note that this test should not be performed before 10 weeks gestation due to a significantly increased risk of a failed result.

What to Expect During Your Appointment

During your appointment, you will undergo a simple blood draw. The positive predictive value of the screening test varies by genetic marker, and may be lower for rare conditions. As with any test, there may be false positives or false negatives.

After Your Results

If your results indicate an increased risk of certain fetal chromosomal abnormalities, it is essential to follow up with genetic counseling and further diagnostic testing and procedures when clinically indicated. QNatal Advanced is not a diagnostic test, but rather a screening test that should be used in conjunction with other tests and medical consultations.

Pricing Options

Alternative UPP pricing is available in Florida, New Hampshire, Massachusetts, Maine, Rhode Island, Vermont, and Texas.

In conclusion, the QNatal Advanced is an important tool for expectant mothers who want to screen for potential chromosomal abnormalities. By understanding how this test works and what you can expect during your appointment, you can make informed decisions about your pregnancy care.
