Virtual online consultations have its own advantages and limitations. Although it is not advisable to prescribe medicine to a patient without an in-person physical examination but in many situations a physician can diagnose and suggest treatment of the illness.

It is best suited when a known patient (already in follow up) wants to get a regular scheduled follow up visit from comfort of home without spending time and money on travel particularly those on long term treatment with controlled or cured disease.

Other scenario where it is extremely helpful is when patients and their relatives are looking for a second opinion or want to know the line of treatment for a particular disease which has been newly diagnosed at some other center.

Even some non alarming new onset disease or symptoms can be consulted online in patients. Doctor may diagnose such a disease that urgently needs physical visit to Hematologist and hence can give a valuable timely advice to attend OPD/Hospital.
