A 37-year-old member asked:

is a drug screening easier to pass than a regular drug test?

NO: A drug screen is a preliminary test that is sometimes part of a "drug test". Usually any positives in the screen are sent to a lab for further testing.
Dr. Paul Pyles
Addiction Medicine 33 years experience
No difference : I'm not sure if there is really any difference. I am not sure I understand your question. Screening tests have room for error and false positives. The gold standard in drug testing is gas chromatography and mass spectrometry. The best way to "pass" any drug test is to not have any of the drug in your system.

What can I expect at a hearing test for my baby?

Dr. Jonathan Jassey
Pediatrics 17 years experience
Passing it: Babies should be passing their hearing tests. If failing it at birth then needs repeat test and might need further testing. If fails hearing later on in life, then might be attributed to wax, fluid in ears, infection, or some other abnormality to the inner ear.

What is nuchal translucency screening?

4 doctor answers7 doctors weighed in
Dr. Erin Alward
Obstetrics and Gynecology 17 years experience
Down screening: Nuchal translucency is measuring the thickness of the baby's neck on an ultrasound in the first trimester. This measurement, along with some bloodwork from the Mom, is a screening test for Down syndrome in the baby. It detects pregnancies that are at increased risk. The only way to know for sure is to do genetic tests on the baby's cells. This can be done with CVS or amniocentesis.

What is a multiple marker screening?

2 doctor answers6 doctors weighed in
Dr. Nicholas Fogelson
Specializes in Gynecology
Genetic Screen: A multiple marker screen uses measurements of four analytes (bhcg, estriol, afp, and inhibin-a) to determine the likelihood that a fetus has down syndrome, t16, or t13 (more severe anomalies than downs). It also screens for neural tube defects, but ultrasound has replaced this screen as a superior modality. Importantly, the test does _not_ tell you if the baby had downs, it only quantifies risk.

Do I need to get nuchal translucency screening?

Dr. Caren Reaves

No: You don't need it, but it is offered to parents if they wish to test for certain abnormalities. The guiding principle is how would the results help you? Would you change the outcome of your pregnancy? Would you use the info to research and prepare? Would the info simply scare you and cause excessive worry? If the results would not be beneficial to you, then you may not want to test.
