Question | Answer |
What is the principle of the gel test? | The controlled centrifugation of red cells through a dextran-acrylamide gel |
What are the beads in the wells do? | Serve as filters for cells----agglutinated cells get caught and non-agglutinated cells go to the bottom of the well |
Tests that are performed by gel (5) | 1. antibody screen & ID 2. ABO & Rh 3.compatibility 4. Reverse serum grouping 5. Antigen typing |
Solid phase testing | Antigen or antibody is fixed on solid matrix and specimen incubated w/coated solid phase. Corresponding Ag/Ab adheres to solid phase |
Solid phase phenotyping | antibody coated onto micro titer plate and patients RBCs added |
Solid phase phenotype--if antigen not present on RBC...... | settles to the bottom of the well |
Solid phase phenotype--if antigen present on RBC... | adheres to sides of the well |
Solid phase--Antibody ID | RBC frags on walls of micro titer well--add pt serum, incubate, wash, and RBCs coated w/IgG----Neg=cells on bottom Pos=cells on sides of well |
