Shows a value collected in 1 unit, but converted to selected standard unit.
Rows 2-4:
Show 2 records for alkaline phosphatase that were collected 1 day apart and are expected to be reported together. Row 4 shows how to create a derived record (average of the rows 2 and 3) and flag it as derived (LBDRVFL = "Y") as well as the record to use as baseline (LBBLFL = "Y").
Rows 6-7:
Show a suggested use of the LBSCAT variable. It could be used to further classify types of tests within a laboratory panel (e.g., "DIFFERENTIAL").
Row 9:
Shows the proper use of the LBSTAT variable to indicate "NOT DONE," when the fact that the test was done was documented.
Row 12:
The subject had cholesterol measured. The normal range for this test is <200 mg/dL. The value <200 may not be used in the normal range variables LBORNRHI or LBSTNRHI; however, an applicant may decide, for example, to enter "0" into LBORNRLO and "199" in LBORNRHI. The applicant must define the appropriate value for all of the normal range variables.
Row 13:
Shows the use of LBUSCHFL to indicate that the test result was obtained from an unscheduled blood collection. In this case, the subject was moribund and a blood sample was taken prior to sacrifice.
Rows 1, 6:
Use records in the SUPPLB dataset example to show biological significance assigned by the investigator for test results.
