DNA fragmentation index in Semen by Flow cytometry (FC) 104620-0
LOINC Code
| LOINC code | 104620-0 | ||
|---|---|---|---|
| name | DNA fragmentation index in Semen by Flow cytometry (FC) | ||
| description | Data for red and green fluorescence are collected by flow cytometry and transformed to determine the degree of red fluorescence in the sperm population, known as the DNA fragmentation index (DFI). DFI measures abnormal chromatin structure. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | DNA fragmentation index | ||
| property | SRto = Substance Ratio | ||
| 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 | Semen = Seminal fluid | ||
| 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 | Flow cytometry | ||
Additional Names | |||
| short name | DNA fragmentation index Smn FC-sRto | ||

| formula (readable) | DNA fragmentation index = (red fluorescence)/(red fluorescence + green fluorescence) | ||
