Prenatal testing Quick guide to common tests

Prenatal testing tests can provide information regarding your child's health
before she or he is birthed. Take into consideration the timing and what
prenatal testing can reveal.

Prenatal testing is supplied in all maternities. Here's an overview of
typical prenatal testing tests:
What it is When it's done What the results might tell you Follow-up
Cell-free DNA (cfDNA) screening
Blood test As early as week 10 Risk of Down syndrome (trisomy 21),
trisomy 18 and trisomy 13 and fetal sex Possible invasive testing, such as
chorionic villus sampling or amniocentesis
1st trimester screening
Blood test and ultrasound 11-14 weeks Risk of Down syndrome
(trisomy 21) and trisomy 18 Possible invasive testing, such as chorionic
villus sampling or amniocentesis; cell-free DNA screening may also be
considered
Quad screen
Blood test 15-22 weeks Risk of Down syndrome (trisomy 21), trisomy
18 and open neural tube defects, such as spina bifida Possible targeted
ultrasound, or invasive testing such as chorionic villus sampling or
amniocentesis; cell-free DNA screening may also be considered


Some health care carriers pick to incorporate the outcomes of initial
trimester screening with the quad display-- although you won't discover the
outcomes of this sequential testing till both examinations are completed and
evaluated.
Additionally, fetal ultrasound usually plays a vital function in prenatal
treatment as well as screening. Early in maternity, ultrasound can be made
use of to verify as well as date a maternity. Later on, ultrasound can be
made use of to detect certain birth defects and fetal anomalies, including
neural tube issues.
Blood tests and also ultrasounds posture limited risks for you and your
infant. If the results of a blood test or ultrasound are positive or uneasy,
your healthcare service provider may recommend an extra intrusive analysis
test-- such as chorionic villus tasting or amniocentesis. These examinations
can be used to detect conditions, yet they lug a small danger of maternity
loss.
If you're concerned concerning prenatal testing or wonder whether you need
specific screening or diagnostic examinations, review the threats and
benefits with your health care service provider.
