Explaining what Antigen, Antibody, and agglutination mean as they relate to blood typing. The basics of how a blood typing card works is also explained.
+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.
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).
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.
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!
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.
This made perfect sense! Thank you so much. I've been trying to understand the concept and this video made it click! Woo!
You’re helping me practice for my physiology final, thank you!
Thank you soooooooo much Dr. It was confusing but now it is perfectly clear. 👏👏👏👌👌👌👍👍👍
all I needed was agglutination and you pointed out perfectly !!! tnx
Made this blood typing so easy to understand....Thank you...
thank god.. now it makes sense... it goes with the same letter but doesn't accept a different letter or else it will attack
amazinglyexplained sir. props to you
This is very very amazing explanation. Millions thanks
Yes, this was a great explanation. Thank you.
Awesome video, Thank You Dr.
Simple but Great explanation. Thanks a lot.
thank you so much. really helpful.
Great video! Thanks for helping my kiddo w/ their homework!
Thanks, great explanation.
Very clear explanation 👌🏻 THANKS
Thank you for helping me understand my test card!!!
Very helpful. Thank you Dr
Great job, thank you!
This helped clarify everything thanks
Thank you soo much for this!!!
Thank you sir now my concepts are clear :)
This helped thank you sooo much!!!!
Thank u soooo much Doc...well explained
Thanks a lot I just understood well
Thank you Sir! Very good video
Thank you doctor
Aha! i get it! ...finally... thank you so much
so thankfull
Very good explanation
What would you call the blood that clumped with the Rh type? Thanks in advance, very helpful video

thaaaaaaaaaaaaaaaanks it`s too easy when you explain it
thank you so much you are greatt
Pls Dr how do I point out its rh type
Whether it's either positive or negative
Watch Dr najeeb lecture (ABO blood grouping)u will get the basic stuff,s
Thanks!

Do people with A blood have IgA antibodies and if so , how does it not destroy it's RBC ?

@@renhartung Thank you so much sir it helped me a with my concepts .
thym well presented sir.
Amazing. Thought I'd never understand it

Thanku sir
Thank youuuuuu
I have no clumping in A, B, D, or Control. What blood type am I?
Those results indicate O negative blood type.
Dr: Antibody's shape is like a Y
Me: But Y
Dr plz upload video abut AB blood group. I mean who can donate blood to them n y
AB+ can receive any blood and AB- can receive all negative blood types.
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!
Type O blood group so it is positive or negative ?
That depends on the reaction in the anti-D circle. The anti-D circle detects whether blood is Rh positive or negative.

is it o+ or o-
That depends... does it have Rh antigens?
If your O type blood does have rh antigens then it is positive and would be O+. If it doesn’t it’s O-

antIGeN
not too clear
jesus Ramirez -- Please help me improve. How could I make this more clear?
Very helpful. Proceed!!
Thank you
