TRANSFUSION MEDICINE- The practice of blood transfusion and blood conservation, complementary activities that ensure the best balance between safety and convenience during emergency care or surgery.
College of AmericanPathologists (CAP) Philippine Blood
U.S. Food and Drug Administration (FDA)
Regulating agency.
CenterforBiologicsEvaluation and Research (CBER) - 1988
Regulates the collection of blood (also its components)
Manufacture of pharmaceuticals derivatives (1 blood unit can save 3 lives)
Develops and enforces quality standards
Inspects blood establishment REMEMBER: Blood is a biological drug
Association for the Advancement of Blood and Biotherapies (AABB)
International association of blood centers, transfusion and transplantation services, and individuals involved in transfusion medicine.
Standards from donor to patient
Provide voluntary inspection and accreditation program for its member institution
College of American Pathologists (CAP) Philippine Blood
Provides a voluntary inspection and accreditation program for its member institutions (same sila ni AABB)
Since most transfusion services are part of the clinical laboratory departments in a hospital, they are included in a CAP inspection.
PHILIPPINES GOVERNING AGENCIES
The Tripartite Summit
Department of Health- NVBSP

PBCC
Education – about voluntary blood donation (both private and public)
NVBSP
Develop fully voluntary system
Promote nationally coordinated network of all the blood services facilities here in the Philippines
Implements quality management system including good practices, good manufacturing practices
Attain maximum utilization of blood
PNRC
To deliver safe and adequate blood supply (to the most vulnerable)
Promote voluntary nonrenumerated blood donation to attain adequacy of the blood
GOVERNING LAWS IN THE PHILIPPINES
Department Order #339-K S. 1988- Creation of the committee on National Blood Services Program (NBSP)
DOHA.O188-A S. 1992-Promulgation of National Blood Services Program (NBSP)
R.A. 7719- National Blood services Act of 1994, Aims to promote a voluntary blood donation
FIVE PROCESSES OF DONOR SELECTION (R2PCP)
Recruitment
Registration/Screening
Physical Examination
Collection
Post Donation Care
60% eligible to donate
450ml of blood/ bag
16 Gauge
M: max. of 6 Whole Blood units/yr
F: max. of 4 Whole Blood units/yr
Age: DOH: 18yrs old – 65yrs old o Harmening: at least 17yrs old (with parental consent) (>66 yrs old can donate if there’s medical certificate)
Deferral period for whole blood:
Philippines: after 3 months
International: after 2 months or 8 weeks
Pheresis
hindi lahat kukunin ▪ 2 units of pheresis deferral period is (after) 16 weeks
Infrequent apheresis
deferral period 4 weeks/1 month
Leukapheresis; plasma; platelet deferral period 2 days
According to FDA in terms platelet pheresis, donate not more than 24x per year
TYPES OF DONORS
Allogeneic
Directed
Autologous
Apheresis
Allogeneic
For general population
Donating blood to samespecies but different individual
Directed
“Taggedamounts” (specific patient; ex. Your family)
You will reserved a certain blood unit for another individual
Autologous
Safest type of donation
Self-donation
For your own future use
Common for scheduled surgery (3 days before the surgery)
Rare phenotypes (such as Bombay, Rh-)
Preserved via Glycerolization then RBC freezing (preserved up to 10 years) Permanent deferred = × allogeneic but autologous
Apheresis
Separation of blood components
Cough and cold = deferred for 48 hours
Multiple puncture mark: according to Harmening = indefinite deferral; DOH = Permanently deferred.
Rash or poison ivy: not a cause for deferral
For female prospective donor: ask if pregnant (temporary deferred; should be 6 weeks after delivery) or not. (or last menstruations).
1st/2nd term of abortion or miscarriage = not deferral
Abnormal or irregular pulse rate: for further evaluation
Athletes: have slower pulse rate (50bpm) = not deferred
LIMITED PHYSICAL EXAMINATION (Get Well Tito Boy PH)
General Appearance
Weight
Temperature
Blood Pressure
Pulse Rate
Hemoglobin and Hematocrit
Hemoglobin and Hematocrit
Most common cause of deferral (low hemoglobin results)
Normal hemoglobin count: 12.5g/dL
Tested using gravimetric method or POCT Machines
Gravimetric Method
Copper Sulfate Method: mostly used for mass blood donation (MBD)
Not reliable (kasi tantsa tantsa lang)
Has specific gravity of 1.053/1.054 (equivalent for specific gravity of blood which has the normal hemoglobin levels)
If blood sink to the copper sulfate = accepted!
If nag float = deferred
Point of Care Testing
-HemoCue Machines- Uses capillary blood
-Automated CBC Analyzers
Allogeneic
Hemoglobin: 12.5 g/dL
Hematocrit: 38%
Autologous
Hemoglobin: 11 g/dL
Hematocrit: 33%
TYPES OF DEFERRAL
Temporary Deferral: - Not be able to donate for a specific period of time
Indefinite Deferral: - Hindi alam kung kailan pwede magdonate ulit kasi baka ang reason ng deferral is dahil sa standards ng FDA and wala pa binibigay na go signal on when you can donate
Permanent Deferral: - Not be able to donate blood forever. - Can still be able to donate for autologous
History of viral hepatitis
In the Philippines, if may hepatitis permanent deferral na
Surface antigen/HBS Ag (+) = indefinite deferral
Reactive for Anti-HBC = deferral
Past/present evidence of HCV = “deferred tlaga”
Post transfusion hepatitis = Permanent or indefinite deferral
Past/present abuse of self injected drugs- Permanent deferral
Hemophilia = permanent deferral
Leukemia, lymphoma= Permanent deferral
Clotting factor deficiencies = permanent deferral
Cancer- Permanent deferral
Nodeferral- carcinoma in situ of cervix, first basal/squamous cell carcinoma, if the person surgically removed capillary thyroid carcinoma
HEPATITIS
Permanent = (+) HBS AG – meaning the person is suffering from acute or active hepatitis.
Temporary = The donor has been diagnosed w/ viral hepatitis before 11 y/o
Indefinite = Donor reacted positively for antiHBC and positive in HBVNAT
12-monthdeferral = Sexual contact or living with a person w/ acute or chronic HBV, Those with other hepa virus (fecal oral = Hepa A & hepa B)
