What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Method: Automated count

What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

Hemoglobin [Entitic mass] in Reticulocytes by Automated count

Hemoglobin

The hemoglobin content of RBCs (MCH) has long been one of the indices reported as part of the complete blood count. However, mature erythrocytes are not sensitive to recent iron homeostasis. The hemoglobin content of reticulocytes, RBC precursors, has more recently been proposed as a better indicator of iron deficiency and early response to iron therapy (Am J Hematol. 2008 Apr;83(4)307-10.)
