antibodies
Compatibility test for incomplete antibodies is done by Coombs' test (I.
D. Gel Technology)
Adverse reactions of blood transfusion are investigated
Blood Components Preparation
-
Red cells
-
Platelet concentrate
-
Fresh Frozen Plasma
-
Cryoprecipitate
-
Plasma
Note: Red cells are preserved in preservative solution Adsol and have extended shelf-life upto 42 days. Platelets are
reserved in the bags of PVC plasticised with trimalliate (Baxter PL 1240) for 5 days at
20-240C in incubator with agitation.
Leukocytes-Reduced Blood Components
Donors leukocytes present in cellular blood components are linked to wide
range of transfusion adverse reactions mainly non-hemolytic reactions, HLA
alloimmunisation and platelet refractoriness.
Techniques for preparing leukocytes reduced components are:
-
New Semi-automated method (using Top and Bottom quadruple bags
and OPTI
System)
-
Washing of red cells
-
Apheresis
Techniques for Preparing Platelet concentrates in this blood bank are:
-
from platelet rich plasma-platelet yield is 5x1010
-
from buffy coat - platelet yield is ≥ 6-7X 1010
with leukocytes reduced to ≤ 107 (log 1, 99% leuko-reduction)
-
plateletapheresis
Platelets are preserved in the bags of PVC plasticised with
trimalliate (Baxter PL 1240) for 5 days at 20-240C in incubator with agitation.
APHERESIS
It is done by CS 300 MS Cell Separator (Baxter)
The following procedures are done:
Merits of Platelet-Apheresis
-
Average yield of platelets is 3x1011 in one unit
-
Plasma volume 200 ml
-
Leukocytes are < 5.5x106 in one units
-
Low risk of alloimmunisation & platelet refactoriness
Common conditions for therapeutic plasma exchange are
-
Myaesthenia Gravis
-
Goodpastures syndrome
-
Acute Gullian-Barre syndrome
-
Waldenstorm's macroglobinaemia
-
Inflammatory / Idiopathic Neuropthy
Plasma Exchange have been done in cases of
Myaesthenia Gravis
and Inflammatory & Idiopathic neuropathies
Common conditions for peripheral stem harvesting
-
Multiple Myeloma
-
Leuka emias in remission
-
Lymphomas
-
Cancers
Peripheral Stem Cells harvesting for autologous
transplantation have been done in cases of multiple myeloma,
Quality Control
-
Computerised data records and achieves
-
Standard Operative Procedures (SOPs) are maintained &
followed
-
Quality control protocols are followed according to the
Drugs & Cosmetic Acts prescribed by Director Drugs Controller (India),
Ministry of Health & Family Welfare (India)
Upgradation of Laboratory
The following equipment are being planned to be added soon:
-
Controlled Temperature Deep Freezer for processing stem
cells
-
Equipment for preservation of Stem Cells in Liquid
Nitrogen at -1800C
-
Blood Irradiator
-
Another Cell Separator-AMICUS
Academic Activities
