(32.5 x 100)/(100+24)
WBC x 100 divided by #NRBC per 100 WBC
WBC approx 26

What is the difference between active, passive, adoptive and natural immunity?
active - natural infection, vaccination
passive - AB derived from another person; in utero
adoptive - transfer of AG from immunized donor to non immunized pt ; transplant

Calculate the creatinine clearance of a 24 hour urine specimen using the following formula and data:
(Uc/Pc) x (TV/1440)
Uc = 650 mg/L Pc = 6.2 mg/L TV = 1600 mL
(650/6.2) x (1600/1440) = 116.5
Which blood groups are known for showing dosage?
Kidd
Duffy
MNS
Rh
Which parasite infects most well water?
Giardia lamblia
Plasma cells evolve from which type of cell line?
lymphocytes
Calculate the dose or doses of Rhogam:
Fetal cells seen = 30
Adult cells counted = 2210
(fetal/Adult) x 100 = % fetal cells
(% x 50)/30 = vials of Rhogam
30/2210 x 100 = 1.36
1.4 x 50/30 = 2.3 + 1 vial
3 vials of Rhogam
