Both the hemoglobin and hematocrit are measurements of the red blood cells. If the hemoglobin is low, would you expect the hematocrit to be low? and
What are the hemoglobin (Hgb) levels indicative of anemia on the CBC?

A CBC (Complete Blood Count) measures a variety of items in your blood. It can be used to determine general health status and to to diagnose and manage various diseases. If you have symptoms such as fatigue, weakness, an infection, inflammation, bruising or bleeding this test can help diagnose the cause.
The CBC blood test is a panel of tests that help doctors to examine each part of the blood. The test can be used in several different ways. In an emergency room situation, the CBC blood test can be used to determine if the patient has a severe infection or is anemic. The levels of specific blood components can alHEMOGLOBIN (HGB)
Hemoglobin is the main transport of oxygen and carbon dioxide in the blood. It is composed of globin a group of amino acids that form a protein and heme which contains iron atoms and the red pigment, porphyrin. As with Hematocrit, it is an important determinant of anemia (decreased), dehydration (increased), polycythemia (increased), poor diet/nutrition, or possibly a malabsorption problem.
so be used to determine if a patient has other medical conditions.
HEMATOCRIT (HCT)
The word hematocrit means "to separate blood," a procedure which is followed following the blood draw through the proper use of a centrifuge. Hematocrit is the measurement of the percentage of red blood cells in whole blood. It is an important determinant of anemia (decreased), polycythemia (increased), dehydration elevated), increased R.B.C. breakdown in the spleen (elevated), or possible overhydration (elevated).
