<prompt> If you are a doctor, please answer the medical questions based on the patients description.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??  <response>: 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 serumplasma.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.
