buffy coat การใช้

• The layer beneath the buffy coat contains granulocytes and red blood cells.
• Buffy coat can be used to increase detection.
• Motile organisms may be visible in the buffy coat when a blood sample is spun down.
• Quantitative buffy coat ( QBC ) is a laboratory test to detect infection with malaria or other blood parasites.
• In such cases the medical technologist may obtain a buffy coat, from which a blood smear is made.
• The layer between the red cells and the plasma is referred to as the buffy coat and is sometimes removed to make platelets for transfusion.
• The buffy coat is usually whitish in color, but is sometimes green if the blood sample contains large amounts of neutrophils ( which are high in green myeloperoxidase ).
• For blood samples, these include centrifugation followed by examination of the buffy coat; mini anion-exchange / centrifugation; and the quantitative buffy coat ( QBC ) technique.
• For blood samples, these include centrifugation followed by examination of the buffy coat; mini anion-exchange / centrifugation; and the quantitative buffy coat ( QBC ) technique.
• The "'buffy coat "'is the anticoagulated blood sample that contains most of the white blood cells and platelets following density gradient centrifugation of the blood.
• Phlebotomy containing a silicone gel; when centrifuged the silicone gel forms a layer on top of the buffy coat, allowing the blood serum to be removed more effectively for testing and related purposes.
• The blood is taken in a QBC capillary tube which is coated with acridine orange ( a fluorescent dye ) and centrifuged; the fluorescing parasites can then be observed under ultraviolet light at the interface between red blood cells and buffy coat.
• A centrifuge can be used in a " hard spin " which separates whole blood into plasma and red cells or for a " soft spin " which separates it into plasma, buffy coat ( used to make platelets ), and red blood cells.
• "' Microfilarial detection "'was accomplished most commonly in the past by the microscopic identification of microfilariae on a direct blood smear, above the buffy coat in a microhematocrit tube ( or capillary tube ), using the modified Knott test, or after millipore filtration.
• After being centrifuged, the following layers will be visible in the conical tube, from top to bottom : plasma and other constituents, a layer of mono-nuclear cells called buffy coat ( PBMC / MNC ), Ficoll-Paque, and erythrocytes & granulocytes which should be present in pellet form.
• "' HUNT Biobank "'was established in conjunction with the HUNT 3-study and is a biorepository of about 21, 500 square feet . plasma, buffy coat, immortalized cells for cell line production, specialized tubes for trace metal / elements-analysis, RNA-tubes and urine.
