RETIC or RETICULOCYTE COUNT

Mature Red Blood Cells live about 4 months.

Your bone marrow is constantly making new Red Blood Cells known at Reticulocytes.  After the Reticulocytes are newly created and in the blood stream, in about two days they develop into mature Red Blood Cells.

Reticulocyte Count (Blood Test) measures the number of new Red Blood Cells in your body, compared to the amount of mature Red Blood Cells, as a percentage.  Also known as Reticulocyte Index or Retic Count.

This test is often ordered by doctors when any type of Anemia is suspected.

The test is a simple blood test.  Results are given as a percentage.  A normal healthy adult ranges anywhere between 0.5% and 2.5%.  Women and Children are normally higher than men. (NOTE: These “Normal” result parameter numbers vary slightly depending on the source of information, and perhaps the lab in which your results are produced).

The above is for an Adult, whereas a newborn will have a normal range from 3.0% to 6.0%.

Hemolytic Anemia typically has an above normal Retic Rate.
Aplastic Anemia, Iron Deficiency Anemia, and Pernicious Anemia are associated with a lower than normal Retic Rate.

Some Anemic conditions are transient in nature.  But they can also be chronic.

If Retic is completely shut down.   There are several suspects that may need to be eliminated as a possibility, or treated if identified and treatable.
