Hemoglobin (Hgb or Hg) is the protein in Red Blood Cells that carry Oxygen.
This is one of the more critical blood tests a CAD needs to have run on a reoccurring basis. One of the basic tests to indicate if you are normal, sliding toward becoming anemic, full blown anemic, or so anemic you may require blood transfusions.
Your Dr will often order a CBC/RBC and Hemoglobin will be one of the results.
Depending on what part of the world you live in, the results may be measure with different values. This might become confusing when people start making comparisons between results in other countries.
In the USA the measurement of mg/dL or Conventional Units is used. Also age and gender come into play when referencing “normal” ranges.

In the UK the measurement of g/L or SI Units is used. We converted the above USA numbers to correspond with that type of measuring system.
Some labs may have slightly different ranges.
