| description | Human Immunodeficiency Virus 2 (HIV2) Antibody Optical Density(OD) to Cutoff (CO) Ratio. Optical density values are providing and indication of the amount of color development during the testing procedure. Color development is proportionate to the antibody concentration in the specimen. A mathematical formula based on the negative controls multiplied by a factor produces a cutoff(CO) value to which the OD of the ptient sample is compared to determine the antibody status. Specimens with OD/CO values greater than 1.0 in an indirect ELISA method are considered positive. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | HIV 2 Ab Signal/Cutoff | ||
| property | RelACnc = Relative Arbitrary Concentration | ||
| 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 | Ser/Plas Ser = Serum Plas = Plasma | ||
| 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 | IA = Immunoassay: Encompasses all immunoassays with a few exceptions, including Immune Blot and Immune Fluorescence, which were created based on historic usage. | ||
