|
Immunohematology:
Donor Defferal - General |
1 year
Possible exposure to hepatitis, HIV or malaria 3 year Possible exposure to malaria (visitor/migrant/prev.diagnosis) Indefinite Defiinite disease or habits strongly associated with bloodborne pathogens |
|
Immunohematology:
Donor Deferral - 1 year |
Hepatitis B Immune Globulin
Poss. exp. to hepatitis, HIV or malaria Tattoo Mucous membrane exposure to blood Skin penetration with instruments contaminated by blood/body fluids Sexual contact with symptomatic individual for any viral hepatitis, confirmed + for HBsAg / HIV or in high risk category After completed therapy for syphilis, gonorrhea or reactive STS Traveled to endemic area for malaria w/wo antimalarial drugs, free of symptoms > 72 hrs. in correctional institution *malarial parasites only in red cells, plasma preps exempt |
|
Immunohematology:
Donor Deferral - 3 years |
Asymptomatic-
Visitor / migrant from area endemic for malaria Previously diagnosed with malaria *malarial parasites only in red cells, plasma preps exempt |
|
Immunohematology:
Donor Deferral - Indefinite |
Viral Diseases:
Viral Hepatitis after age 11 + confirmatory test for HBsAg Repeatedly reactive test for anti-HBc Donated only unit to recipient who developed post transfusion hepatitis, HIV or HTLV Present/Past infection of HCV, HTLV or HIV Evidence of parenteral drug use Other Diseases: Received dura mater or pituitary growth hormone of human origin, family history of CJD or risk of vCJC History of Chagas' disease, babeiosis |
|
Immunohematology:
Maximum Collection of Whole Blood |
no more than 10.5 mL of whole blood per kg. of body weight, including samples
|
|
Immunohematology:
Wating Period for Whole Blood Donation |
56 days
|
|
Immunohematology:
Common Blood Anticoagulants, Additives & Solutions |
CPD - anticoagulant
citrate, phosphate, dextrose 21 day expiration CPDA-1 - anticoagulant cpd & adenine 35 day expiration Additives(enhance rbc survival) contain dextrose, adenine, sodium chloride among others 42 day expiration Rejuvenating Solutions contain pyruvate, inosine, phosphate and adenine Restores 2, 3-DPG and ATP added during storage or up to 3 days after expiry can freeze unit or store at 1-6˚C if using within 24 hrs. (must wash cells before use) |
|
Immunohematology:
Autologous Donations |
no age limit
Hct - 33%, Hb 11g/dL No bacteremia Must be labeled "for autologous use only" Segregated from allogenic units |
|
Immunohematology:
(Autologous Only) Low Volume Donations Volume to Draw formula |
ex. 90 lb donor
(90 lb/110 lb) x 450 ml (standard) = 368 ml or (donor wt. in kg/50) x 450 |
|
Immunohematology:
Low Volume Collections |
If 300-404 mL drawn, label as
Red Blood Cells Low Volume If < 300 mL drawn, adjust coagulant *components may not be made from these units |
|
Immunohematology:
Amount of Anticoagulant for Low Volume Collections |
368 x 14% = amt. of anticoagulant
368 x .14 = 51.5 (52 ml) needed 63 (standard) - 52 = 11 ml to remove from primary bag into attached satellite bag prior to draw |
|
Immunohematology:
Hemapheresis/Apherisis Criteria |
Donor criteria same as Whole
Waiting Period of 48 after apheresis to donate Whole max 500 mL (600 mL if > 175 lbs. Limits # of donor exposures |
|
Immunohematology:
Hemapheresis/Apherisis Methods |
Centrifugation
Withdrawal of whole blood, remove selected fraction and remaining reinfused into donor Filtration removal of only plasma through a membrane Adsorption removal of only a selected constituent of plasma with reinfusion of remaining |
|
Immunohematology:
Apheresis Types |
Cytapheresis - cells
Plasmapheresis - plasma Plateletpheresis - platelets Leukapheresis/ Granulocytapheresis - leukocytes/granulocytes |
|
Immunohematology:
Donor Criteria for Apheresis |
