**How long does a unit of blood remain usable after being entered?**
24 hours
**Storage temperatures for components**
- **Red cells:**
CPDA: 35 days
Adsol: 42 days
Storage temperature: 1-6°C
- **Whole blood with CPDA-1:**
1-6°C for 35 days
1
,**Blood transfusions for infants should be...**
Less than 7 days old
**Irradiated RBCs must be used within what timeframe?**
28 days or until the expiration date, whichever comes first.
**Why is blood leukoreduced?**
To prevent febrile transfusion reactions.
**Storage temperatures for components**
- **Platelets (PLTs):**
Room temperature (20-24°C)
5 days with continuous agitation; transfuse within 4 hours of pooling
- **White blood cells (WBCs):**
20-24°C for 24 hours
- **Fresh frozen plasma (FFP):**
Frozen at -18°C for 1 year; usable for 24 hours after thawing
- **Cryoprecipitate (Cryo AHF):**
Stored at -18°C for one year
- **AHF or factor VIII concentrate:**
Usable for 24 hours after thawing at 1-6°C (room temperature for VIII)
**Administer VIII and fibrinogen within...**

, 4 hours after pooling.
**True/False: RhIG at 28 weeks can cause the mother to have low titer anti-D.**
True
**True/False: Blood from mother to child must be irradiated.**
True
**True/False: 37°C crossmatch is required to detect ABO errors.**
False (Room temperature)
**Premature infants primarily require transfusions due to...**
Blood loss from laboratory tests.
**True/False: When phenotyping, use a positive control that is homozygously positive.**
False (Use a heterozygously positive control to show weak reactions)
**Rouleaux and cold auto will make the auto control positive. How can this be distinguished?**
Distinguish by warming the sample, examining under a microscope, or performing saline
replacement.
**What will react with polyspecific AHG and C3 monospecific AHG?**
Cold auto antibodies
**Cryoprecipitate is primarily used today to replace what?**
Fibrinogen
**True/False: AB= patient can only receive AB plasma (+ or =).**
3
, True
**What must be done to intrauterine transfusions?**
They must be fresh, CMV-negative, irradiated, and collected with CPDA.
**Which component is used when PT and PTT are prolonged?**
FFP (Fresh Frozen Plasma)
**True/False: Lewis antibodies react at room temperature and sometimes at 37°C and cause in vitro
hemolysis.**
True
**How long is the sexual partner of an IV drug user deferred from donating?**
One year
**If a patient has antibodies to A, B, A,B, and H but types as O, what is suspected? How is it resolved?**
Suspected: Bombay phenotype.
Resolution: Test with anti-H lectin (Bombay individuals will not react since they lack H antigens).
**If a patient forward types as B and backtypes as A, what is suspected? How is it resolved?**
Suspected: Acquired B phenomenon.
Resolution: Patient is typically type A1 with GI issues where bacteria alter RBC antigens.
Autologous testing shows that the patient's anti-B will not react with the acquired B antigen on their
RBCs.
**If a patient forward types as a weak A, has a weak reaction with anti-A1, and a strong reaction with
anti-AB, while showing no reaction with anti-A1 lectin, what is suspected? How is it resolved?**
Suspected: Patient with anti-A1.
Resolution: Type with A2 cells (+ indicates NOT A2; = indicates it is A2).
