What is the definition or description of: antibody screen (anti rh)?

Simple blood test: Antibody screening during pregnancy is essential to identify blood group and antigen incompatibilities that might be exist between a mother and her developing child. The screen involves determining the mothers blood group type: a, b, ab, o and rh status (pos and neg). About 10 percent of caucasian women (much lower in non-caucasian ethnicities) are rh negative entering pregnancy. ...Read more

Mother Baby Blood Type Mismatch (Definition)

Mother Baby Blood Type Mismatch, also known as ABO incompatibility, occurs when a pregnant mother has a different blood type than the developing baby. Exposure to the baby’s blood type, either from that pregnancy or a previous sibling, causes the mothers body to develop antibodies to the blood type. The condition is dangerous as antibodies can cross the placenta and cause anemia (blood cell destruction), jaundice, or fetal ...Read more

Recently i took a HIV DNA PCR test and results were detected and reference range not detected, my HIV antibody screen test came back neg I am worried?

Recent exposure?: Follow up testing is required. Pcr tests have a false positive rate of 3-10%. If you had a recent exposure, it is possible that repeat testing will show antibody to become positive and there is a true HIV infection. If it does not, it is likely a false positive. ...Read more

I am an L&D RN.  I have an Rh+ pt who has turned up with a + antibody screen, 1 day before her scheduled C-section.  Her screen was -  in June. What??

Some ideas: She may have become sensitized to one of Dad's antigens other than Rh-D which is the usual problem one. The lab may be using more sensitive sera. The situation is fairly common. ...Read more

27wkspreg Rh negPositive antibody screen today was neg a month ago had a prev ectopic and chem but had shot after What does this mean for this preg?

Rh factors: If your "shot" after your ectopic pregnancy was Rh immune globulin , which in Rh negative women is protective against problems from Rh disease in future pregnancies, the chance of a problem with this pregnancy is minimal. If you have had other pregnancies prior to your ectopic without Rh immune globulin given, continued testing is appropriate. ...Read more

What risks do me and my baby go through when antibody screen is positive?

I assume Rh?: If you are rh negative and your partner is rh positive then you are trying to make antibodies against your baby. This is somewhat dose dependent so if you had a prior child, abortion, or miscarrige you are sensitized. Normally, after delivery, get medication to kill any rh positive cells in your body. So the major risk is if you had a prior pregnancy and did not get the medication. ...Read more

Can receiving the rhogam shot 4 weeks ago today cause a positive antibody screen??

Can receiving the rhogam shot 4 weeks ago today cause a positive antibody screen??

Rhogam shots: "Rhogam" is immune globulin given to Rh negative women after a pregnancy. The Rhogam shot is in fact Rh positive antibodies, and if the "antibody screen" is done soon after a Rhogam , a "positive antibody screen" will result. This does not mean the individual is in fact "Rh positive", and is only the result of the Rhogam shot. ...Read more

I just had an HIV 1/2 eia antibody screen w/ reflexes. Can you explain how this test works? Are there any better tests?

I just had an HIV 1/2 eia antibody screen w/ reflexes. Can you explain how this test works? Are there any better tests?

Viral Testing: To test for many infections we look for antibodies (your body's reaction to something new or foreign). In the case of HIV infection these antibodies can take three to six months to be positive on a test. This old fashioned test is a reliable and common screening tool. But, it is not the best test if one is possibly exposed. We now send HIV genetic tests which can be positive by day 21 post expos. ...Read more
