Very helpful. It could be better though. It could be understandable a lot more if you insert a few videos about how the agglutination works, the blood typing or even a video showing how the clumps are formed. Nevertheless, a very interesting and informational video!
IgA is a type of antibody. The A in IgA does not refer to what antigen it will attack, it just separates IgA from other types of antibodies like IgM, IgG, and IgD... these designations refer to where these antibody types can be found and what their job is. IgA antibodies for example are considered secreted antibodies, they get secreted into mucus/seruos fluids and tears to help protect mucus membranes. Hope that helps. Another example are IgE antibodies, their job relates to allergic reactions and defense against parasites. Regardless of whether they are IgA, IgE, IgM, or IgD there are billions of possible alien antigens that a given antibody will bind to. Hope this helps.
So if I understand correctly if you’re O negative your third circle should look exactly like your fourth circle because they use O negative antigen as the control. Is that correct?
Yes, the third circle should not clump up (agglutinate) if you are Rh negative. In that third circle are antibodies against Rh antigen. If you were Rh positive those antibodies would react with your blood cells and cause agglutination (agglutination means the clumping of cells caused by antibodies).
+bryonaknightt Remember that the "clumping" you see is called agglutination--- If we see agglutination in the circle for Rh that means that the person's blood is Rh positive. So, their blood type could be O+, A+, B+, or AB+ (depending on what the other circles of the test show). In other words, the plus sign in a blood type means that the person is Rh positive... They have Rh on their red blood cells. If we see a minus sign O-, A-, B-, or AB- then they are negative for Rh... They do not have Rh on their red blood cells. Please let me know if that helps.
My husband and I both did an at home blood type test. The tests came up that we are both O pos, but he had a strong agglutinate reaction (blood looked clumpier), while mine was they typical agglutinate reaction (not as clumpy) according to the instructions that came with the test. I'm curious what this means? Does this mean he has more RH than I do? Or does it not mean anything at all and it's just a reaction? Thanks so much!
Interesting that you saw a difference in reaction between the two of you... There are a few possible reasons for this. The most interesting is that you may have a mix of Rh- and Rh+ genes (if that were the case then your red blood cells might only express half of the Rh+ proteins than a person with both genes for Rh being Rh+). You might be able to track that down if you can find out the blood types of your parents and maybe their parents (if anyone is Rh- in blood type than the mix I'm writing about is possible). Other possibilities involve the amount of blood added to the card and the amount of antibody what was on the card at the start. Thank you for sharing with me.
anybody ever hear of the rare kidd antigen my hubby has it when i was pregnant i developed antibodys in my blood my kids were in danger but they were all ok
Yes, the Kidd antigen system (Jk antigens). Named after a woman named Kidd who's child suffered hemolytic disease of the newborn although mom was Rh positive. Hope you and baby are well.
