| description | 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.) | |

| component | Hemoglobin | |
| property | EntMass = Entitic Mass | |
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | |

| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | |
