Question

Blood Typing Here is the activity we were going to do in lab. Please read and fill in the data table: Obtain a slide and place a drop of anti-A, anti-B, and anti-Rh (in three SEPARATE spots) on the slide. Choose a synthetic blood sample and mix a drop of blood with each of the antisera (A, B, and Rh). Mix the blood and antiserum together using a clean toothpick. Don't reuse toothpicks or mix samples. The antiserum contains the antibodies. The presence of clumping means that the blood has that antigen. The absence of clumping means that the blood does not have the antigen. For example, clumping in A, B, and Rh means that the blood is AB+. Draw a datatable below and record the data you collect for your blood sample. Serum added Clumping? What type of antigens are present on the cell? (A, B, Rh?) A-antibodies Yes B-antibodies No Rh-antibodies Yes What is the blood type of this patient? To whom can this patient donate blood?

Answer 1

there is mistake in table. the correct table will be ........because if b antibody mixing do not show clumping then antigen B will be absent and if antibody a is showing clumping then antigen a is present in blood sample similarly Rh antigen is also present in blood as blood is showing clumping in Rh antisera

SERUM ADDED CLUMPING WHAT TYPE OF ANTIGEN PRESENT OF CELL A-Antibodies B-Antibodies Rh-Antibodies Yes No Yes

so. 1 Blood group of the sample is A Rh positive (A +ve)

2 this patient can donate blood only to A+ and AB+ blood group individuals because only these individuals will be having both A and Rh antigen
