Yo ... ur Answer: autoimmune disorders are challeching because, it can potentaily effect the cells and the tissue of the body systemic, organ, and blood. moreover, there are over 80 idetified many are overlapping and non- specif. to get the correct autoimmune diagnosis must be follow PT history, physical evedience, and serological finding.

Your Answer: genetic and environmental exporsure Answer: genetics and environmental factors Question 19 10 / 10 pts 1, A 32-year-old woman presents to the clinic for her initial obstetrics visit, about 10 weeks into her pregnancy. She is in a monogamous relationship. (1) Should an HIV test be part of her initial blood work? Why? 2. An infant is born, and its initial antibody test is positive for HIV. (2) Does this mean the infant is infected? What would be the more appropriate test to detect HIV in this infant? Your Answer: 1-yes she should be tested for HIV,2- because mother and fetus is the very high and coomon that she will pass the virus to fetus, also the CDS recommonds anyone who is the age between 13-64 sould be tested for the disease. 1-no it does not mean the fetus is positive for the disease. 2-apporpiate test will be PCR test which detect the presence of the trace amount in the DNA of the infected fetus, regardless of the outcome the fetus will have the mothers antibodies,however the PCR test will give alternative startegy to ditermine if the virus is presence in the fetus's . 1. Yes. Transmission from mother to infant is the most common way that children become infected. The CDC recommends all people between ages 13 and 64 be routinely screened for HIV. Earlier detection and treatment lead to better outcomes. 2. No. The polymerase chain reaction (PCR) test is a nucleic acid test that can detect HIV DNA. It tests for the presence of the virus, rather than the antibody, which is helpful in diagnosing HIV infection in infants born to infected mothers. These infants would have their mother’s antibodies whether or not they have been infected. Correct!
