What is thrombocytopenia? is there any treatment or is this condition fatal?

Low platelets: This is an abnormality found on lab testing. It may be anything from a mild reduction in platelet numbers due to immunity, allergy to quinine in a gin and tonic, medication effect, a big spleen, or much else to a life-threatening effect of grave blood disease or chemotherapy. See if your physician can help you find the cause and stay proactive.
