My father is 72+ and during a recent heath check up his esr rate was 83, eusonophyl 7, and platlet 0000. Other parameters were normal.He had mild dry cough while the test was done. The cough subsided subsequently wwith antibiotic RESPICURE, but relapsed after a week. Again antibiotic AZITHRAL has been given. He is taking it for 4 days now but not having much effect. The dry cough increases in the evening. However he doesnt have any fever during any time of the day and the cough doesnt disturb while he lies down or sleeps. He takes medicine for high bp and a drug called Ecosprin 75 for some heat ailments as suggested by local cardiologist for the last 6 yrs. Are the readings ok or needs further drill down. Is there anything to worry about?
