spavlis Posted May 30, 2012 Share Posted May 30, 2012 What is the testing methodology used for platelet pH testing?Does anyone use blood-gas analyzers for this test?ThanksStephanie Link to comment Share on other sites More sharing options...
SMILLER Posted May 30, 2012 Share Posted May 30, 2012 Thank goodness, all of our platelets are in 5-packs from our supplier, pooled in some magic aseptic way that does not require us to do any type of testing here such as pH.In the old days, when we had to pool individual units, we simply used pH paper (and also had to document QC for the paper every day of use by using a standard). If the pH was above something like 6.0, it was OK to pool and transfuse. But check current AABB and FDA regs!Scott Link to comment Share on other sites More sharing options...
Bill Posted May 30, 2012 Share Posted May 30, 2012 In the old days, we were cited by TJC for using pH paper--the reason was that it was not sensitive enough. We gave up using random platelets at that time. Link to comment Share on other sites More sharing options...
Kashmira patel Posted May 31, 2012 Share Posted May 31, 2012 We use PH meter in a blood center setting for QC of apheresis platelets. Link to comment Share on other sites More sharing options...
AkshayR Posted September 8, 2012 Share Posted September 8, 2012 A standard bench top pH Meter is used at our establishment. Link to comment Share on other sites More sharing options...
GCH LAB RAT Posted September 10, 2012 Share Posted September 10, 2012 At one hospital that I work, we used the blood gas analyzer, but the down side to this was that it took approx 5 mins for unit of platelets being tested. At the other hospital I work, we "used" a mini Lab pH meter. But now our platelets come from our supplier already pooled and pH tested. This was a way to reduce the bacterial contamination. Boy am I happy!!!!! Link to comment Share on other sites More sharing options...
R1R2 Posted September 10, 2012 Share Posted September 10, 2012 I thought pH testing of platelets was no longer acceptable? Link to comment Share on other sites More sharing options...
GCH LAB RAT Posted September 11, 2012 Share Posted September 11, 2012 It isn't. That's why most blood suppliers went to pooling and pH testing (using the FDA approved methods) before shipping platelets. Gnapplec 1 Link to comment Share on other sites More sharing options...
cthherbal ☆ Posted September 15, 2012 Share Posted September 15, 2012 It isn't.

cthherbal ☆ Posted September 15, 2012 Share Posted September 15, 2012 Transfusion Services that do not collect platelets themselves, can no longer use pH/glucose, but must use a method of equal or better sensitivity then culture-based methods for Bacterial Testing of platelets. Currently this rule applies to Random Donor Platelets. Apheresis platelets are already tested at the blood collection center and currently do not require re-testing at the hospital prior to transfusion. Visual inspection must pass prior to issuing product. Link to comment Share on other sites More sharing options...
