| Iron
deficiency anemia is the most common of the anemias and is usually
due to bleeding. In women, iron deficiency may be due to heavy menstrual
periods, but in older women and in men, the bleeding is usually
from disease of the intestines. In children and in pregnant women,
the body needs more iron, and iron deficiency may be due simply
to not eating enough iron in the diet. Iron deficiency may also
result from some extreme diets. Treatment of iron deficiency usually
involves iron supplements. In older women and in men, there is usually
also some further testing to determine why the person is iron deficient.

The
Comprehensive Metabolic Panel (CMP) is a frequently ordered
group of 14 tests that gives important information about the current
status of your kidneys, liver, and electrolyte and acid/base balance
as well as of your blood sugar and blood proteins. Abnormal results,
and especially combinations of abnormal results, can indicate a
problem that needs to be addressed.

The Complete Blood Count (CBC)
is used as a broad screening test to check for such disorders as
anemia (decrease in red blood cells or hemoglobin), infection, and
many other diseases. It is actually a panel of tests that examine
different parts of the blood. Results from the test provides the
broadest picture of your health
Serum iron level
- measures the level of iron in the liquid part of your blood.
Total Iron Binding Capacity (TIBC)
- measures the amount of transferrin, a blood protein that transports
iron from the gut to the cells that use it. Your body makes transferrin
in relationship to your need for iron; when iron stores are low,
transferrin levels increase, while transferrin is low when there
is too much iron. Usually about one third of the transferrin is
being used to transport iron. Because of this, your blood serum
has considerable extra iron-binding capacity, which is the Unsaturated
Iron Biding Capacity (UIBC). The TIBC equals UIBC plus the serum
iron measurement. Some laboratories measure UIBC, some measure TIBC,
and some measure transferrin.
Composed of iron and protein, Ferritin
is a storehouse for iron in the body. Measurement provides an accurate
picture of how much iron you have available in reserve. It is used
to evaluate anemia and for diagnosing iron deficiency. Low Ferritin
is a sign of iron deficiency. Ferritin is high with inflammation,
infection, liver disease, iron overload, certain amends and certain
cancers (leukemia and lymphoma).
Transferrin is the main protein
which transports iron in blood. Blood levels are used to evaluate
anemia and deficiency. High transferrin levels are found in iron
deficiency, pregnancy, and in those taking birth control pills.
It is low in liver disease, kidney disease, cancer, chronic inflammation,
hereditary transferrin deficiency, or when there are excessive amounts
of iron in the body.
Hemoglobin
The hemoglobin test is an integral part of your health evaluation.
The test is used to measure
the severity of anemia (too few red blood cells) or polycythemia
(too many red blood cells), monitor the response to treatment, and
help make decisions about blood transfusions. |
