Philippine Red Cross Internship Notes, Study notes of Medicine

Detailed notes on the internship experience at the philippine red cross western visayas regional blood center. It covers various aspects of blood services, including donor recruitment, screening, collection, component preparation, testing, storage, and distribution. The document delves into the storage requirements, indicators, and quality control measures for different blood components such as packed red blood cells, whole blood, platelet concentrate, fresh frozen plasma, and cryoprecipitate. It also discusses the principles of enzyme immunoassay (eia) for detecting hiv and hepatitis b, as well as the order of appearance of hepatitis b serological markers. The document serves as a comprehensive reference for understanding the operations and procedures involved in a regional blood center.

microplate transport and microplate dispense area
Station for wash buffer and washer
Incubators and photometers
PRINCIPLE OF EIA (Enzyme Immunoassay)
HIV p24 antigen and antibodies to HIV-1 and HIV-2
in human serum or plasma
ACQUIRED IMMUNODEFICIENCY SYNDROME
Is a virus inducing infectious disease characterized
by strongly depressed immunity.
HBsAg - in the serum or plasma indicates an
infection caused by Hep B virus
It is the first marker to appear and may be observed
2 or 3 weeks before clinical and biological
symptoms of the disease.
Hepatitis C virus - is recognized as being the main
cause of non-A and non-B viral hepatitis. HCV
infection is characterized by an acute and chronic
form that may lead to cirrhosis and hepatocellular
carcinoma.
Causative agent of Syphilis - Treponema pallidum
subsp. pallidum

Quadruple blood bag - Aliquot TYPES OF BLOOD BAGS:  Karmi or Terumo type  63 mL of anticoagulant  55% plasma of your blood’s total volume  44% RBC  1% WBC and plts COMPUTATION OF EXPIRY DATE  Extraction date + Anticoagulant (35 days) - Number of days in the month = Expiration date PROGRAM 1  Light spin: 2400 rcf (relative centrifugal force)/rpm, 4 mins. at 22 degrees  For PRBC and Plt rich and plasma product PROGRAM 2  Heavy spin: 3600 rcf/rpm, 8 mins at 22 degrees  For plt concentrate and fresh frozen plasma products, plt poor PROGRAM 3  Heavy spin: 3600 rpm, 8 mins at +3 degrees  For cryoprecipitate ACD-A: Acid Citrate Dextrose Formula A (21 days) CPD: Citrtae Phosphate Dextrose (21 days) CP2D: Citrate Phosphate Double Dextrose (21 days) CPDA1: Citrate Phosphate Dextrose Adenine (35 days) CPDA1 with SAGM (Saline, Adenine, Glucose, Mannitol ( days) on quadrop of triple blood WHOLE BLOOD blood drawn directly from the body from which none of the components, such as plasma or plts has been removed PLATELET FUNCTION to prevent and stop bleeding; tiny blood cells that help your body form clots to stop bleeding PLATELET PLUG prevents more blood from leaving the body as well as any outside contaminants from getting in. PLT PLUG FORMATION also called PRIMARY HEMOSTASIS is the first of two steps needed for hemostasis HEMOSTASIS how the body prevents blood loss when injury happens. PRBC are produced by removal of majority of plasma forming unit of whole blood are what remains of whole blood after the plasma and plts have been removed. PLT CONCENTRATE prepared by using a centrifuge to separate the plt-rich plasma from the donated unit of whole blood contains about 60 mL of plasma and small numbers of red blood cells and leukocytes. FRESH FROZEN PLASMA plasma that has been frozen so it can be stored and used later contains coagulation factors at the same concentration present in plasma. CRYOPRECIPITATE highly concentrated source of Fibrinogen; 5 FACTORS INVOLVED: Fibrinogen, Factor VIII, VWF, Factor XIII and Fibronectin.; cryo-precipitated antihemophilic factor (Heavy spin: 3600 rcf for 8 mins at 3 degrees (Program 3) CRYOSUPERNATANT Cryo-poor plasma, cryoprecipitate depleted, cryoprecipitate reduced plasma Used to prevent or control bleeding in people whose own blood does not clot properly. (Hemophilia A (lack of FVIII) and VWF disease (lack of VWF) ALIQUOT to split up single unit, the blood bag is the spin off at the hospital and split in to smaller portions prior to use in a neonatal transfusion. Purpose of RBC sa tube is for crossmatching.
