I too am begining to show orange blood whenever I have a scratch or have a pro-time finger stick.  I am 71 and this has never happened before.  What could be the causes?  Anemia??  Leukemia?  I have what is called \"thrombophilia\" and I have taken coumadin for 47 years after suffering a massive thrombophlebitis in my leg after 2 months of birth control pills.  This was in 1964.  It went into a Pulmanary Emboli, but I survived.  Now what??
Hi, Thanks for asking. Based on your query, my opinion is as follows.1. Orange blood is due to mixing of Red blood cells with excessive amount of serum/plasma.2. No, it is not either anemia or leukemia.3. Thrombophilia is increased incidence of clot formation. When it is more, it will increase incidence of clot. Due to your previous risk of having a clot formation, you need to be on Coumadin to avoid future risk. 4. If doubtful, you can get a hologram and peripheral smear to evaluate for anemia or leukemia. Hope it helps. Any further queries, happy to help again.
