###Human: Kindly explain my dual test taken for pregnancy. ###Assistant: Hi. I can understand your concern. According to your test results (attachment removed to protect patient identity), negative factors are: PAPP-A levels are elevated. Beta hCG levels are low. Positive factors are your age is below 30 years and nuchal translucency is normal. Now the possible steps can be followed are as 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 in a 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, the possibility of the chromosomal disorder is more and you may need to terminate the pregnancy after confirming with your doctor. Take care.
