<s>[INST] Hi doctor, my son had a platelet count in the reading 491 m3/ul when he is 3 weeks old The report show question mark in PLC clump, immature gran, NBRC. May i know what does it mean? But doctor said everything is ok, now the insurance company query about these. The blood test was done due to prolong jaundice.
