Is Gender A Factor In Pertussis

Is there a genetic test in UK that can tell if a person is a poor metabolizer with Clopidogrel having two copies of each of the CYP2C19 gene.?

Would there be a (big) difference in the measurement if a 12wk old fetus compared to a 9wk old fetus? The gestational age would be determined in u/s?
Yes: An first trimester sonogram is fairly accurate at dating a pregnancy (within a margin of error of about a week).

Is a woman with sc blood genotype a sickle cell carrier or patient. And what is the health implication of this especially during pregnancy?
Hgb SC: Is a sickle cell syndrome but the genetics are different. A woman with HGB sc will pass either a HGB s gene, or a HGB c gene to her child. It is important to know what kind of HGB the father has-he should have a hemoglobin electrophoresis to find out how the child might be affected. Pregnancy complications are rare, but the baby can have a low weight, and rarely there are complications for the mom. ...Read moreSee 1 more doctor answer

This number is added to the random risk of 4% that any pregnancy has of an unexpected event (cleft palate, premi, other defect). ...Read more
