Second Trimester Screening Test
Already had harmony test, afp, first trimester screening and they were all very low what might a dr suggest if soft markers are found on anatomy scan?
Reassurance!: If all that's found is a soft marker, and your screening and cell free dna results are normal, the most likely answer is that the soft marker is a normal variant. However if there is a finding consistent with a birth defect, that might merit further investigation, such as diagnostic testing within amniocentesis. ...Read more
Examples are: colonoscopy for colon polyp or cancer; mammograms for breast lesions or cancer; psa a blood test that could indicate enlargement of cancerous prostate tissue; blood sugar or hemoglobin a!c for diabetes. Many think that scanning the whole body will pick up a cancer--in all likelihood, it will not. There also is no good blood test, yet, ...Read more
My 1st trimester screening came back very low 1 in 3, 000. I just took the harmony genetic test. Is there any chance my risk can change to high risk?
Not likely: Your numbers are quite good. The 1 in 3000 is based on your first trimester screen which is a probability. The harmony test is based on the fetal dna in your blood. Therefore, it has a higher detection rate than the first trimester screen, and in theory could change--but not highly likely given your good numbers. ...Read moreSee 1 more doctor answer
I had a normal first trimester screening and harmony prenatal test. Is an AFP blood test necessary? Can it come back high risk?
The msAFP is: To assess the risk of open neural tube defects i.e. Spina bifida, which is not tested by harmony or the first trimester screen. It is up to you if you would like to be screened for ntds. Keep in mind that, if detected, these defects can be repaired by a skilled pediatric neurosurgeon while the baby is still inside you. Speak to your obgyn and make an informed decision. Hope this helps. ...Read moreSee 1 more doctor answer

If the 1st trimester screening for Down syndrome was negative, how much does an echogenic focus at 20 week screening factor in?
Should i be worried if soft markers were found in anatomy scan when harmony, AFP and first trimester screening were very low risk?
I'm sure it's hard : Not to worry till your OB can gather enough additional information to confirm or rule out a problem. However, it also assures you that you & your baby are receiving excellent medical care & that all needed tests &/or referrals will be offered to you in a timely fashion. Try to stay positive & healthy. You may not have. Been able to process everything your OB said at first, so ask him/her again. ...Read moreSee 2 more doctor answers
