Hemoglobin may be less and more. In men 13 to 18 g/dl, and In women, 12 to 16 g/dl should be.The hematocrit test, also known as a packed-cell volume (PCV) test, is a simple blood test.
low hemoglobin may indicate ‘anemia’ and high HG can be caused by smoking, dehydration, etcIf a patient is severely dehydrated, the hemoglobin and hematocrit will appear higher than.
