Gerrard Teoh Hematology & Medical Clinic

Welcome to HMClinic

Hematology is the field of Medicine that is concerned with conditions of the BLOOD and/or BONE MARROW.

The functions of our blood include

  1. Supply of oxygen & nutrients to the whole body

  2. Regulation of blood clotting & bleeding

  3. Immunity & healing

Every single organ in the body depends on blood. Blood is essential for life. Hence, Hematological disorders can affect virtually every organ in the body. And vice versa, almost every medical condition can have direct or indirect effects on the blood and/or bone marrow.

We look healthy and good because our Blood and Immune System constantly nourish, protect, heal and repair our bodies.

Take care of your Blood and Immune System, and your Blood and Immune System will take care of you.
