Difference between bleeding time and clotting time?
Clotting refers to the hemostasis process that occurs in the body when there has been some injury to a blood vessel & blood loss needs to be stopped. It is a process that involves many steps & is vital to our survival. People whose blood will not properly clot, or coagulate, are in danger of bleeding to death. For example, people with the hereditary condition, hemophilia, are missing one of the several factors needed for normal blood coagulation. Agglutination refers to the clumping of red blood cells that occurs when different blood types are mixed together. It involves a chemical reaction between antigens on the surface of red blood cells & protein antibodies in the plasma, or liquid, part of the blood. Certain blood types cannot be safely mixed together due to this antigen-antibody reaction. The fact that mixing different blood types together can cause agglutination has been used as a means of typing blood, i.e., determining just what blood type a person has.
Patient's serum influenza virus and red blood cells are mixed in a tube What happens if the patient has antibodies against influenza virus?
Hemagglutination?
Prawns heart carries which type of blood?
Mixed blood
What does the red blood cell looks like in distilled water?
Normally red blood cells look like flat disk, witch is compressed in the center. So that they have more surface area when they get exposed to oxygenated air from alveoli and secondly they can get folded, when they squeeze through capillaries, witch are smaller than the size of red blood cells. When we put them in the distilled water, they will get swollen, like a boll, as water will enter the cells due to higher oncotic (osmotic, you can say) pressure inside the cells.
Hemagglutination-inhibition test description?
It is the measures of the ability of soluble antigen to inhibit the agglutination of antigen-coated red blood cells by antibodies. In this test, a fixed amount of antibodies to the antigen in question is mixed with a fixed amount of red blood cells coated with the antigen (research on passive hemagglutination). Also included in the mixture are different amounts of the sample to be analyzed for the presence of the antigen. If the sample contains the antigen, the soluble antigen will compete with the antigen coated on the red blood cells for binding to the antibodies, thereby inhibiting the agglutination of the red blood cells.
What is the process that occurs when two incompatible blood types are mixed causing clumping of blood cells?
Agglutunation
What is the clumping together of red blood cells when unlike incompatible types of blood are mixed is due to antibodies in the plasma and antigens on the?
On the surface of red blood cells Take A type blood, for instance. It has antigens against B type blood contact on its cell surface.
What is MXD percent in a blood test?
mxd stand for mixed cells in t he blood
Can somebody leave white blood cells in the hospital?
yes,it will be mixed in blood
What is mxd test blood?
MXD test blood is the measure of mixed cells in the blood. Also meaning, the measure of Lymphocytes in the blood.

How is blood cross matching performed?
A test tube of the patient's blood is sent to the blood bank and spun down, so that the red cells are in the bottom and the plasma is on top. The plasma is separated into a separate tube, and then a few drops of red cells are placed into another tube. The red cells are washed first, which means that they are mixed with saline and spun in a centrofuge, and then the saline is removed. This gets rid of excess proteins which might cause a false reaction. Once the cells are washed, more saline is added to make a .8% suspension. The following test tubes are set up: 1. One drop of the red cell suspension + 2 drops of Anti-A antiserum 2. One drop of the red cell suspension + 2 drops of Anti-B antiserum 3. One drop of the red cell suspension + 2 drops of Anti-D antiserum 4. Two drops of patient serum + 1 drop of red cells with A antigen 5. Two drops of patient serum + 1 drop of red cells with B antigen Each tube is mixed gently, then spun for 15 seconds in a centrofuge, then checked to see if the cells in the tube can be easily resuspended (negative) or if they are all stuck together in a clump (a positive reaction). This is done with each cross-match to confirm the patient's ABO and Rh blood types, although, if the patient has had their blood typed in the lab previously, the lab worker may choose to only do the first three or the last three tubes just to double-check that the results the first time are OK. An antibody screen is set up, which can take place either in a test tube or a special gel card. Reagent red cells are added to the tube or the card, and these cells are already known to contain a variety of antigens. The patient serum is added to the cells, and a reaction will be seen if the patient has antibodies. As for the cross-match itself; On each bag of donor blood, there is a long tube of blood that is clamped at intervals to make sections. A section is removed, the blood poured into a labelled test tube, and the blood is diluted to a .8% suspension. 2 drops of the donor blood are put into another labelled test tube with 4 drops of the patient serum, and this is mixed and then spun for 15 seconds in the centrofuge. Compatible blood will be easily suspended, incompatible blood will be stuck together in a clump. The tube is checked microscopically to make sure that there aren't tiny clumps of cells.
What is the chemical composition of whales' blood?
Like human blood, whales' blood is mostly made of red blood cells and plasma, with a much smaller amount of white blood cells. Plasma is mostly water, but has proteins, fats, and other chemicals mixed in.
Breakdown of recipient's red blood cells when incompatible bloods are mixed?
agglutination

If the patients serum Rickettsia guinea pig complement sheep red blood cells and anti sheep red blood cells are mixed in a tube What happens if the patient has epidemic typhus?
Rickettsia grow
How is Detection of the abnormal protein rheumatoid factor in the serum found?
There are two ways of measuring Rheumatoid factor in bloodThe Agglutination tests. In this test blood is mixed with minute latex beads that have been covered with human antibodies. If there is RF, the beads clump together or agglutinate. Another agglutination test uses sheep's blood that has had its red blood cells covered with rabbit's antibodies, then mixes the blood being tested with it . If there is RF in the blood sample, the red blood cells clump together. This method is often used to confirm the presence of RF.The Nephelometry test. In this test a blood sample is mixed with antibodies cause the blood to clump if RF is present. A light beam from a laser is directed through the sample containing the mixture and the amount of light blocked by the blood sample is measured. The more clumping that occurs, the cloudier the sample and less light to pass through the tube.
