H and H (Hemoglobin and Hematocrit) Test-Reference Range

H and H (Hemoglobin and Hematocrit) test, also called Hemoglobin, Hgb, and Hb test, is often used to help diagnose conditions affecting red blood cells (RBCs). It measures the amount of hemoglobin in your blood.

Hemoglobin is an iron-containing protein in red blood cells which carries oxygen to body’s organs and tissues, and transports a small portion of carbon dioxide from organs and tissues to the lungs.

The normal ranges for hemoglobin are as follows:

  • The normal levels for men range between 13.5 and 17.5 grams per deciliter.
  • The normal levels for women range between 12.0 to 15.5 grams per deciliter.

Lower levels of hemoglobin with low RBC count and low hematocrit indicates anemia, caused by bone marrow disorders, kidney failure, chronic inflammatory diseases, iron deficiencies, B12 deficiencies, etc.

Higher levels of hemoglobin with high RBC count and high hematocrit indicates polycythemia, caused by lung disease, smoking, dehydration, polycythemia vera, kidney tumors, congenital heart disease, etc.
