Levothyroxine absorption in Serum or Plasma by calculation 90804-6
LOINC Code
| LOINC code | 90804-6 | ||
|---|---|---|---|
| name | Levothyroxine absorption in Serum or Plasma by calculation | ||
| description | The percent absorption of levothyroxine, as determined based on the incremental increase in Ser/Plas thyroxine [LOINC: 90803-8], the volume of distribution [LOINC: 90802-0], and the dose of levothyroxine that was administered [LOINC: 18615-5] | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Levothyroxine absorption | ||
| property | MFr = Mass 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 | 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 | Calculated | ||
