Platelets Donation Risks
Last year I got a hematoma after donating platelets. Today, I had to stop a donation due to hematoma risk. Is donating once or twice a month too much?
NO: NO- your blood is always checked before donation. You can certainly donate once a month without issues; however, I advise consulting with your PCP regarding hematoma (usually related to the venipuncture).
Pheresis: Is essence is a process where blood is "filtered" to extract either cellular products, red cells, white cells or a substance for either re-infusion (cell) or removal a macroglobulin in plasmapheresis in waldenstrom's macroglobulinemia.
Yes, watch set up: The entire "plumbing" set for the machine comes out of one (sterile) package, then the IV solutions are opened and added (one time use). When you are all done, the entire works (minus the platelet collection bag!) is taken down and disposed of.
What are some ways to speed up a platelet donation? I give every two weeks and many people finish faster than me. Can I speed up the process?
Normal platelet...: ...Counts are from 150 to 450 k, so it is possible that someone has 3 times more platelets than you but both of you are normal.
How can you speed up a platelet donation? I give platelets once a week and I know some people finish way faster. Is there a way to speed it up?
No: It is all dependent on the machine which spins your blood to skim the platelets. You can ask the tech to speed it up if possible, but I do not think it is.
Not by much: Platelet apheresis returns almost all of the non-platelet blood components to you, so WBC and RBC levels usually do not change at all. Platelet count may drop briefly, but our bodies rapidly manufacture them, since it does not know if you donated them or if you sustained an injury that used them, it can adjust level within a few hours.
Is the infusion of citate during a platelet donation safe? I have read that the comlication of hypocalcemia can be life threatening.
Safe: Citrate does chelate calcium and can cause symptoms of hypocalcemia. However, in a person healthy enough to donate blood/platelets, the liver can metabolize citrate fast enough so that it is not a problem. You may take calcium containing antacid to hasten recovery. I applaud you for donating blood and doing your civic duty. Wish you good health.
Essential: Thrombocytosis is a seemingly benign over-production of platelets but has a tendency to lead to clots and strokes, and may be a true myeloproliferative (leukemia like) disorder. You need to see a hematologist/oncologist to seal the diagnosis and discuss the need for treatment and options.
Complicated.: This is a great question. The major worry of platelets being too lowis unexplained bleeding into the head, which can be very serious. This risk is present at different levels for different patients. It depends on quite a bit of variables: age, recent injury, other illnesses, current bleeding, chance of platelet recovery, etc. Clearly if there is troublesome bleeding, they are too low.
Clumping together: Platelets are sticky cells thus they can stick and clump together. As a result of platelet clumping, platelet counts reported by automated counters may be much lower than the actual count in the blood because these devices cannot differentiate platelet clumps from individual cells.
