Additional Info
- Use this code if the thrombocytopenia is not related to the other options or the cause is unknown.
- Regarding a "threshold" to identify low platelets:
- The usual lower reference value (which represent the value for which 97.5% of NORMAL people are above, is 150,000. This means then that 2.5% of normal people DO have <150,000 platelets. This makes it tricky to give a single reference value below which we'll call them thrombocyotpenic.
- Further complicating the situation, normals have relatively little fluctuations in their counts. Thus, a person whose usual count is 300,000, will actually be "relatively thrombocytopenic" if their count falls to 180,000.
- THUS, in light of this, we will define, for our use, thrombocyotpenia as a lab finding (not necessarily as a disease or as a cause of bleeding) if either of the following is true:
- Count <120,000
- Fall by >100,000 from baseline
Includes
- Post-transfusion purpura (PTP)-a rare complication of blood transfusion characterized by the precipitous onset of severe thrombocytopenia and absolute refractoriness to platelet transfusions. PTP occurs 3–12 days after blood transfusion, often in a multiparous female or previously transfused recipient. Combine with Iatrogenic, transfusion reaction (incompatibility reaction) (any type)
