Mandatory Infectious Disease Testing
a. HIV antibody (anti-HIV) donor screening test or HIV antigen/antibody (Ag/Ab) combination test
b. Hepatitis B surface antigen (HBsAg)
c. Hepatitis B core antibody (anti-HBc)
d. Hepatitis C antibody donor screening test (anti-HCV)
e. Hepatitis C ribonucleic acid (RNA) by donor screening or diagnostic nucleic acid test (NAT)
f. Cytomegalovirus (CMV) antibody (anti-CMV)
g. Epstein-Barr Virus (EBV) antibody (anti-EBV)
h. Syphilis donor screening
i. Toxoplasma Immunoglobulin G (IgG) antibody test
When would Transplant center is requesting pre-surgical nodes for tissue typing
your donor received a lot of blood products and steroid treatments
If 6 antigen mismatches are identified on your donor it means?
less likely chance of rejection; less likely chance of finding a recipient; Allocation will occur to national patients last
Total blood volume calc
donor’s weight in Kg divided by 0.015.
Round to the nearest tenth.
Total Plasma Volume calc
donor’s weight in Kg divided by 0.025.
Round to the nearest tenth.
Hemodilution- Total Infused
calculated amount of all infusion given to the patient by adding all blood and colloids given within
48 hours prior to blood draw
Round to the nearest tenth
Hemodilution- What period of time do you need to account for with blood and colloids
48 hours prior to blood draw
Hemodilution- Plasma Infusions
calculated amount of colloids given within 48 hours prior to blood draw
and adding all crystalloids given 1 hour prior to blood draw
Hemodilution- What period of time do you need to account for with Crystalloid
1 hour prior to blood draw
