Early life and education Dhallan earned an M.D. and a Ph.D. in biomedical engineering at Johns Hopkins University, then began a residency in radiation oncology at Massachusetts General Hospital. Later, after deciding to found the startup firm Ravgen, he studied business at the University of Pennsylvania's Wharton School, receiving an MBA in 2007. Career According to a 2007 ''CNN'' profile, after Dhallan had begun his residency and fathered two children, his wife suffered two miscarriages, which caused him to be “struck by how little information was available to women who experienced complications during pregnancy....so he resolved to invent a better prenatal diagnostic exam.” Amniocentesis provides 100% accurate results, but has a one-in-200 risk of causing a miscarriage and cannot be carried out until 15 or 18 weeks into the pregnancy; existing non-invasive prenatal screenings, meanwhile, have low ac ...

Prenatal Diagnosis
Prenatal testing consists of prenatal screening and prenatal diagnosis, which are aspects of prenatal care that focus on detecting problems with the pregnancy as early as possible. These may be anatomic and physiologic problems with the health of the zygote, embryo, or fetus, either before gestation even starts (as in preimplantation genetic diagnosis) or as early in gestation as practicable. Screening can detect problems such as neural tube defects, chromosome abnormalities, and gene mutations that would lead to genetic disorders and birth defects, such as spina bifida, cleft palate, Down syndrome, Tay–Sachs disease, sickle cell anemia, thalassemia, cystic fibrosis, muscular dystrophy, and fragile X syndrome. Some tests are designed to discover problems which primarily affect the health of the mother, such as PAPP-A to detect pre-eclampsia or glucose tolerance tests to diagnose gestational diabetes. Screening can also detect anatomical defects such as hydrocephalus, anencephal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attending Physician
In the United States and Canada, an attending physician (also known as a staff physician or supervising physician) is a physician (usually an M.D. or D.O.) who has completed residency and practices medicine in a clinic or hospital, in the specialty learned during residency. An attending physician typically supervises fellows, residents, and medical students. Attending physicians may also maintain professorships at an affiliated medical school. This is common if the supervision of trainees is a significant part of the physician's work. Attending physicians have final responsibility, legally and otherwise, for patient care, even when many of the minute-to-minute decisions are being made by house officers (residents) or non-physician health-care providers (i.e. physician assistants and nurse practitioners). Attending physicians are sometimes the 'rendering physician' listed on the patient's official medical record, but if they are overseeing a resident or another staff member, th ...
