LOINC Code
| LOINC code | 31111-8 | ||
|---|---|---|---|
| name | Reticulocyte production index | ||
| description | The reticulocyte production index also called the corrected reticulocyte "count" (it is really a percentage, adjust the observed count for the degree of anemia based on the hematocrit using the formula Recticulocyte index= Reticuloctye% *( Hct(observed)/45) where 45 is taken to be the "standard" hematocrit Reticulocyte production index= Reticulocyte index X correction factor" where correction factor is applied as follows HCT Correction factor 36-45 1.0 26-35 1.5 16-25 2.0 < 15 2.5 | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Reticulocytes/100 erythrocytes^^hematocrit adjusted | ||
| property | NFr = Number Fraction | ||
| 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. | ||
| system | Bld = Whole blood | ||
| 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 | ||

Associated Observations | |||
LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations. | |||

| last change type | MIN - change to field other than name | ||
| change reason | The system of RBC had been an oversight. Reticulocytes are red blood cells, but the system of interest is blood | ||
