| name | Abnormal leukocytes/Leukocytes in Specimen by Flow cytometry (FC) | ||
| description | Hematopoietic malignancies can express on their surface particular subsets of cluster of differentiation (CD) antigens which deviate from the expression patterns of normal mature leukocytes. This result indicates the numerical fraction of all leukocytes examined in the flow cytometry study whose expression pattern was abnormal. The specific patterns found are reported under a different result | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Leukocytes.abnormal/Leukocytes | ||
| 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 | XXX | ||
| 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 updated | 2.79 | ||
| last change type | NAM - change to Analyte/Component | ||
| change reason | Release 2.79: COMPONENT: Triggered by Coll w SCT: This is a specific fraction case where the denominator is percentage or /100. Because the logic is that the percentage piece is captured by Property: NFr (Numeric Fraction), and by Unit: %, therefore, it is redundant to include "100" in the component; | ||
