LOINC Code
| LOINC code | 29593-1 | ||
|---|---|---|---|
| name | Cells.Ki-67 nuclear Ag/100 cells in Tissue by Immune stain | ||
| description | Ki-67 is a proliferation marker that correlates with flow cytometric S-phase. Breast cancer specimens with greater than 20% Ki-67 positivity will generally have a high S-phase fraction, which is an unfavorable prognostic marker. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Cells.Ki-67 nuclear Ag/100 cells | ||
| 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 | Tiss = Tissue, unspecified | ||
| 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 | ||
| method | Immune stain | ||

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 | Updated Component from "MIB-1 Ag" by adding "Cells." to correctly represent that a number fraction is being reported, and changed "MIB-1" to "Ki-67 nuclear", because MIB-1 is the monoclonal antibody that detects the Ki-67 antigen and MIB-1 itself is not the antigen | ||
