Hi doctor, The patient is my wife.
Hi. Kindly find answers of your questions as below. Your total leukocyte count and platelet were low initially. But gradually it has been improved so suggest recovery of any unnoticed infection. Moreover, the peripheral smear examination report was normal (attachment removed to protect patient identity) and not showing any abnormal cells that warrant further investigation. You have to still repeat CBC after few days. The TSH is high, so hypothyroidism should be ruled out. For that repeat TSH estimation after few days and investigate with T3, T4 estimation as well. If there is any abnormality, then gradually all counts go down or high and peripheral smear shows abnormal cells if blood cancer is present. It is difficult to say one reason for low WBC. But the infection can be possible. If no cause is evident then ANA estimation can be done to do work up for autoimmune disease. If your CBC values do not fall within the range in the next few days then hematologist can be consulted for a detailed evaluation. If hypothyroidism is confirmed then Levothyroxine should be started.
