Preparing Coombs control cells is very easy. To about 10 drops of washed O Positive red cells add 5-6 drops of anti-D antisera. Incubate at 37C for 15 minutes. Wash 4 times then prepare a 3 to 5% cell suspension. To verify reaction, add two drops of AHG into test tube and one drop of newly prepared Coombs cells. Centrifuge on High for 15 seconds,,,should get 1 -2 + reaction.

What is a Coombs' test?
An indirect Coombs' test looks for antibodies to someone else's red blood cells in the patient's serum
What does Coombs indirect mean?
Coombs indirect refers to the indirect Coombs test, a laboratory procedure used to detect antibodies against red blood cells in a patient's serum. This test is commonly employed in blood transfusion compatibility testing and in diagnosing hemolytic anemia or Rh incompatibility in pregnancy. By mixing the patient's serum with red blood cells of known antigenicity, the test identifies whether antibodies are present, which could lead to agglutination of the red blood cells.
What do the Coombs' tests detect?
The Coombs' tests detect the antibodies responsible for the destruction of the red blood cells
What is the best ratio of diluting Anti-D in the preparation of coombs control cells?
The recommended ratio for diluting Anti-D in the preparation of Coombs control cells is typically 1:100 (1 part Anti-D to 100 parts diluent) for optimal performance. This ratio helps ensure sufficient binding of Anti-D to red blood cells while minimizing background reactivity in the Coombs test. Adjustments may be necessary based on specific assay requirements and validation studies.
What liver function test indicates excessive breakdown of red blood cells?
Elevated levels of indirect bilirubin in liver function tests indicate excessive breakdown of red blood cells. Indirect bilirubin is a byproduct of the breakdown of hemoglobin from red blood cells, and increased levels suggest an increased rate of red blood cell destruction.
Where does coombs disease come from?
Where does coombs disease come from?A blood disease called autoimmune hemolytic anemia happens when antibodies destroy your own red blood cells faster than your body can make them. You can get it because of: Diseases like lupus and leukemia. Infections such as mononucleosis.
Cells control center?
The cells control center is the nucleus
What does the body use to control within cells?
The body uses enzymes to control reactions within cells.
What chemicals does the nucleus control in the cells cytoplasm?
your butts cells
Why is it called the control center this is for science I need an answer fast?
In cells control center of cells is the nucleus. It controls the cellular activities
What is indirect bilirubin?
Indirect bilirubin is a type of bilirubin that is unconjugated, meaning it is not bound to other compounds in the liver. It is produced when red blood cells break down and is then processed by the liver to be converted into direct bilirubin for excretion. High levels of indirect bilirubin in the blood may indicate liver or gallbladder issues.
What is indirect respiration?
indirect respiration is a gaseous exchange that involves two phases: a. external respiration - exchange of gases between environment and tissues. b. internal respiration - exchange of gases between the tissues and body cells juiysiey ",
