Blood Collections, Donor Reactions, & Donor Testing Flashcards
Obj. 1: Compare and contrast the three donor classifications:
- Autologous
- No upper or lower age restrictions
- May NOT cross-over into homologous if not used by patient
- Low volume units must be labeled appropriately and anticoagulant adjusted
accordingly
Obj. 1 Compare and contrast the three donor classifications:
- Directed Donation
- If not used by patient, may be put into general inventory
- Request must be placed by patient’s physician
Obj. 1: Compare and contrast the three donor classifications:
- Homologous/Allogenic
- Makes up nearly 100% of hospitals’ inventories
Obj. 2: State the donation interval for the following types of donation:
a. Autologous whole blood donation
b. whole blood
c. Double red cell (RBC Apheresis)
a. At least 3 days between donations, no sooner than 72 hours before intended
use
b. 8 weeks
c. 16 weeks
Obj. 2: State the donation interval for the following types of donation:
d. Platelet apheresis
e. “Occasional” plasmapheresis
f. “Serial” plasmapheresis
d. 2 days (2x/wk., 24x/yr.)
e. Not more than once in 4 weeks
f. 2 days (2x/wk., 104x/yr.)
Obj. 3: Discuss the special requirements for platelet apheresis donors with regards to:
a. Deferral time for aspirin consumption
b. Minimum platelet count of donor
a. 2 days
b. > 150,000
Obj. 4: State the minimum acceptable levels for the following tests in allogeneic and autologous donation:
a. age
b. weight
c. temperature
d. pulse
e. blood pressure
f. hemoglobin/hematocrit
a. 17 y/o; 16 y/o with written permission; no upper age limit
b. > 110 lbs.
c. < 37.5C or 99.5F
d. 50-100 bpm (athletes may be lower)
e. Systolic < 180 mmHg
Diastolic < 100 mmHg
f. 12.5g/38% female allogenic
13.0g/39% male allogenic
11g/33% autologous
Obj. 5: State the deferral period for the various vaccinations/immunizations as stated in lecture and study questions
No deferral
- Flu shot, tetanus, toxoids/killed synthetic, bacterial, rickettsial
2-week deferral
- Rubeola, mumps, polio, typhoid, yellow fever, Hep A or B
4-week deferral
- Rubella, chicken pox
8-week deferral
- Smallpox
12 month deferral
- HBIG
2-day
- COVID
Obj. 7: List at least 10 reasons for a permanent deferral.
- History of a positive test for HIV, HCV, or AIDS
- History of hepatitis after age of 11
- Confirmed positive test for HbsAg or repeatedly positive for anti-HBc, anti-
HTLV - Creutzfeldt-Jakob Disease (or family history of)
- History of cancer, leukemia, hemophilia, sickle cell anemia, thalassemia
- Tegison (teratogenic drug)
- Treated with growth hormone
Obj. 8: Describe the procedure for a whole blood donation including arm preparation, blood collection, and post-phlebotomy care instructions for the donor
Obj. 9: Differentiate among mild, moderate and severe donor reactions, including symptoms and treatment
Obj. 10: Describe a hematoma reaction including how it occurs and how to treat it
Localized collection of blood under skin, caused by the needle going through the vein
Treatment: remove needle, apply pressure and raise arm above head, apply ice for 5 minutes
Obj. 11: Describe the donor reaction that is only seen during apheresis donations
Citrate toxicity: from anticoagulant infused when blood is returned to donor; binds calcium, causing hypocalcemia; counteract with calcium supplements
Obj. 12: Describe the transport requirements for blood that will be processed into components from collection site to the component processing lab
1-6C
Obj. 13: List the tests (serological and infectious disease) required for allogeneic, autologous and pheresis donations
