Posted May 19, 20187 yr comment_73353 Hello I want a book which describes calculations in blood bank as HB of PRBCs unit -platelets in unit -fibrinogen in FFP OR CRYO .......etc
May 23, 20187 yr comment_73404 Mollison. All that info is general. If you get apheresis plts, they usually have the plt count attached. I don't know of anyplace that will give you numbers for fibrinogen in each individual unit. There are standards which the components need to meet (usually 75% of units tested must meet the std criteria).

You have to do the actual counts of cells if you want that data. I don't know how you would calculate the hgb in a unit of blood other than testing. YOu can calculate how much plasma you want to give; platelets are known to give an "increment" based on the count in the bag - as long as the patient is not actively using/destroying them. As I said previously, there are standards that blood components need to meet when they are QC'd. Units need to be tested - rbcs for hct, plts for count, plasma/cryo for fibrinogen. Every component is not tested, the vast majority are not. I think you are seeking info that is not pertinent.

May 25, 20187 yr comment_73428 Take your fibrinogen result and multiply it by the volume of the bag. x mg/dL x dL/100 mL x vol (in mL) of your cryo = total mg of product Someone should correct this if in error, but it seems logical to me. the dLs and mLs cross each other off leaving only mg/product. This is pretty basic stoichemistry. Wouldn't hurt to get a chem book or the AABB Technical Manual.
