Platelets help blood to clot. A normal count is 1.5 to 4.5 lakh per microlitre. A low count is called thrombocytopenia.
Symptoms
- Pin-point red spots (petechiae) or bruises on the skin
- Bleeding gums, nose bleeds, blood in urine or stools
- Heavy menstrual bleeding
- Many people have no symptoms and the low count is found on a routine test
Common causes
- Infections – dengue, malaria, viral fevers
- Immune thrombocytopenia (ITP) – the body destroys its own platelets
- Medicines, alcohol, liver disease with a large spleen
- Pregnancy-related causes
- Bone marrow disorders – aplastic anaemia, leukaemia, MDS
- "Pseudo-thrombocytopenia" – a lab artefact; a repeat sample in a citrate tube may be normal
Treatment
Depends on the cause and the count. ITP may need steroids, IVIG, or newer tablets (eltrombopag); many people with mild ITP need only monitoring. Platelet transfusion is reserved for bleeding or very low counts.
