The clients blood typing reveals Rh antigens what blood type would the client have Rh receptive, Rh negative, Rh resistant, Rh positive
ABO blood types: A positive persons have "a" antigens on their blood cells, b-positive have "b". And ab positive have both. "o" blood cells have neither. ...Read more
ABO Type&Screen, does "negative" antibodies mean NO antibodies at all or no UNexpected antibodies for the reported blood type?
No unexpected ones: It means no antibodies against the red cells of the cross match. E.g., if you have type A blood, you would have anti-B antibodies as a matter of course. The potential donor blood is type A, but you also have no antibodies against any of the other antigens (outside of ABO system) which mY be found on red blood cells. ...Read more
Why is blood type o universal donor when it has both anti-a and anti-b antibodies? Wouldn't blood type a have issue receiving o as a result of anti-a?
Plasma: With transfusuion, the blood is given, not the plasma. The plasma has the antibodies. ...Read more
Me and my wife's blood type is AB+, she is now at week 13 and blood test showed antibodies. She had a miscarriage before. Should we be worried?
Not for Rh antibody: You did not indicate which antibodies your wife has, but she should not have any Rh antibodies, if she is truly AB+ (the + indicates the presence of the Rh antigen). Since she has Rh antigen, she should not develop antibodies to this antigen. However, there is the possibility that she could have other antibodies if she was exposed either through previous pregnancy or transfusions. ...Read more
Blood group antibody: At birth a kid with blood group o negative will have no original antibodies to any blood group. There may be some transient anti-a or b passed along with shared maternal antibodies, but these will disappear over a few months. Specific testing might detect them, but for no real benefit. In life we can develop original anti a or b from things we eat. ...Read more
Test accuracy: Every test we do has a margin of error, due to both the nature of the test itself or how people behave when they collect samples, and the biologic variation between people. That said, the antibody tests for HIV perform quite well and in the setting of a suspect exposure are largely conclusive. However, the nucleic acid tests are far more specific than antibody-based tests can be. ...Read more
Will I be able to donate blood, after testing + for hep b core antibody and neg for hep b surface antigen?
Absolutely not: Will not be able to donate, sorry... ...Read more
I had blood tests done and my hepatitis b surface antibody QL reactive, hepatitis b surface antigen non-reactive, what does it mean?
Need entire panel.: You're best off using HealthTap Prime to answer your question. You can upload the entire lab report & discuss with a doctor. So far, test shows you have antibodies but no antigen: means either you're in the "window period" after exposure when the virus goes "underground" or you were given a vaccine which made you immune to hepatitis B. We need the pre-core "e" test. Use HealthTap Prime to disucss. ...Read more
Is a HIV antibody/antigen blood test conclusive at 10 weeks after possible exposure? Negative at 10 weeks. Should I test again?
Conclusive: No need to test againGet a more detailed answer ›
Took HIV Antibody 1&2 Test and P24 Antigen test 10 days after PEP. Results non-reactive. A bit early. All other blood panel metrics normal. Thoughts?
Not conclusive: These results are reassuring; it is unlikely you were infected. However, the results are not conclusive. Following PEP, it is necessary to test for HIV longer than otherwise, maybe up to 4 months. (PEP is great when needed, but it prolongs the time of uncertainty about whether infection occurred.) Discuss with the clinic or doctor who prescribed the PEP and follow his or her advice. ...Read more
Bloods done for HIV at GUM clinic. Would this test for antigens or antibodies or both? Tested 15 months out.
Doesn't matter: At 15 months, it doesn't matter. Any and all HIV tests that exist will detect HIV infection if more than a few weeks have passed and for sure after 3 months. If your test result was negative, for sure you don't have HIV. That said, my understanding is that most UK GUM clinics routinely use the duo test for antibody and antigen. But why don't you just call the clinic and ask? ...Read more
Neg p24 antigen test and neg HIV1/2 antibody test at 11wks post exposure. Can I trust these blood tests and finally have some peace of mind? For HIV
You are fine: Please trust these results. I'm sorry you had a scare, but I hope that you will have confidence that you're not infected with HIV and that you will put this behind you. I also hope that you will treasure the memory of having shared love. Human love is never perfect and always involves risks. But I hope you'll find real joy with another person, and share safe intimacy when the time is right. ...Read more
No: It should be a constant genetic character of your genomic make up of your blood it would not change it may of been measured incorrectly some minor antigens can be detected which were not detected earlier but the major blood group should not change if you had a blood transfusion you may see different types of blood but that is unusual. ...Read more
Blood test: Blood is mixed with antibodies to the proteins that determine blood type. If the blood clots, then the blood has that protein on it. If it doesn't clot, the protein isn't present. For example, I draw your blood and mix it with some a antibody, some b antibody, and some rh antibody. If it clots with all of these, your blood type is ab+. If it clots with none of them, it's o-. ...Read more
Get it Tested - If..: Blood type refers to thousands of proteins on the surface of cell membranes, as recognized by antibody proteins. Abo and rh types were the first 2 & most important (in terms of transfusion reactions) characterized historically. There are hundreds more "types". However, there is no known practical reason for the testing. It is always tested/retested if you ever donate blood or are to be given cells. ...Read more
A Fad - Probably Not: Blood type refers to thousands of proteins & glyco-proteins on the surface of cells, especially red blood cells. Abo and rh types refer to only the first 2 & most important (in terms of transfusion reactions) characterized historically. There are hundreds more "types", the reason blood cross-typing is always performed before transfusions. Types reflect genes - but clear basis for selecting foods. ...Read more
Rare occurrence: Blood group h or bombay phenotype is a rare variation in which the person is genetically deficient in the enzymes needed to make the base product for ABO blood group antigens. Such people make antibodies to all blood types except blood group h and thus would find it very difficult to find compatible blood. ...Read more
By getting tested: A person usually has to do a blood test in order to find out her ABO/Rh blood type. Any lab can do the test, but it requires a doctor's order, and may or may not be covered by insurance. The other way for a healthy person to learn her blood type is to donate blood (the blood center will find out the blood type). People who have an IDENTICAL twin can just ask what the twin's blood type is. ...Read more
