Kindly explain my dual test taken for pregnancy.

Question

Hi doctor,

I just did a dual test. I am worried right now, please help. The report is as follows:

Gestational age is 12 weeks and six days, crown-rump length 64.8 mm, nuchal translucency MoM 1.7 mm, nasal bone is seen, free beta-hCG 60.47 mIU/mL, PAPP-A 6020 mIU/mL. Method: ECLIA (fully automated electrochemiluminescence system). I have attached the report. Disorder screen positive cut off: trisomy 21 (Down) 1:250, trisomy 18/23 1:250.

Please explain.

Thank you.

Hi,

Welcome to icliniq.com.

I can understand your concern. According to your test results (attachment removed to protect patient identity), negative factors are: PAPP-A (Pregnancy-associated plasma protein A) levels are elevated. Beta HCG (Human chorionic gonadotropin) levels are low. Positive factors are your age is below 30 years and nuchal translucency is normal. Now, the possible steps can be followed like a dual test can be performed till 14 weeks, better to repeat the test after 48 hours preferably in a standard laboratory. If the results fall within the normal range, repeat the ultrasound after one week. If everything is normal, you can continue the pregnancy. If on repetition also test gives screen positive result, the possibility of the chromosomal disorder is greater and you may need to terminate the pregnancy after confirming with your doctor.

I hope this information helps provide some insight into your symptoms.

Please do not hesitate to reach out if you have any further questions or concerns.

Thank you.
