Bleeding times

Recommended Posts

Does anyone out there still do bleeding times? If your facility doesn't, did you just discontinue it altogether or did you switch to another testing method?

We haven't for some time.  It always was a crappy test for so many reasons.  For general platelet function, we have a PFA-100 , and  for P2Y12 (e.g. Plavix) and aspirin, we use a Verify Now (Accriva).

Yes we still do them on a rare occasion.  One of those archaic nearly useless tests that some doctors can't get away from.

What's a bleeding time?

In a way, it is exactly what it says.

Punctures (usually three) are made, usually on the inside of the forearm, using a device that makes the punctures a "precise" depth.  The blood derived from the punctures is soaked up using absorbent paper, such as filter paper, making certain that the wounds are not wiped, so that no forming clot is disturbed, and the whole is timed from the punctures being made, to the time the bleeding stops.

I only saw it performed a couple of times, and that was at lease thirty years ago, so I have no recollection as to what was the normal time or range of times.

I was being facetious.  I haven't seen a bleeding time in decades.

I am working at Korea General Hospital, but the bleeding time is meaningless.These days, Platet function test or equipment is PFA 200 ...P2Y or Asprin with Verify equipment and ADP with A-100.
