Laboratory -Routine Clinical Labs Example 1

This example illustrates the use of the LB domain variables.

	Lab Panel Name LBCAT Pre-populated	HEMATOLOGY; CLINICAL CHEMISTRY URINALYSIS

Record the date of specimen collection using this format (DD-MON-YYYY).	Specimen Collection Date LBDAT LBDTC	_ _ / _ _ _ / _ _ _ _
Record the laboratory name.	What was the name of the laboratory used? LBNAM	_________________

Lab Test Name LBTEST LBTEST and LBTESTCD	WBC RBC, cells,Protein Urinalysis Cholesterol, Albumin, Creatinine <LBTEST codelist>
Record laboratory test result.	Result LBORRES	_________________
Record or select the original unit in which these data were collected, if not pre-printed on CRF.	Unit LBORRESU	g/L mg/dL mg/L U/mL ug/L sec RATIO <UNIT codelist>
Record the lower limit of the reference range of the lab test.	Normal Range Lower Limit LBORNRLO	_________________

Record where the lab result fell with respect to the reference range (i.e., HIGH, NORMAL, LOW).	Comparison to Reference Range LBNRIND	High Normal Low <NRIND codelist>
Record whether lab results were clinically significant.	Was this result clinically significant? LBCLSIG	Yes No <NY codelist>

The SDTM LB dataset used the UNIT codelist for LBORRESU and LBORRESU. The LBLOINC variable contains a code from the Logical Observation Identifiers Names and Codes (LOINC) database that identifies a specific laboratory test. were included by the sponsor. The LOINC to LB Mapping Codetable, available at https://www.cdisc.org/standards/terminology/controlled-terminology, may be used to identify appropriate CDISC CT values for a test with a particular LOINC code.

LBNRIND was added to indicate where a result falls with respect to reference range defined by LBORNRLO and LBORNRHI. LBSTNRC was used to populated a normal range values that are character values for an ordinal scale (e.g., “NEGATIVE") LBORNRLO, LBORNRHI, LBSTNRLO, and LBSTNRHI are null for these types of tests.

Rows 1 -4:	Show records for common tests to evaluate hematogoly. The sponsor used LBCAT (HEMATOLOGY) to group these tests.
Rows 2-3:	Show 2 records for alkaline phosphatase done at the same visit, a day apart. LBPTFL is set to "Y" for both rows because each result is based on a sample from a single point in time.
Rows 5,7:	Shows records for common test under the grouping CLINICAL CHEMSITRY.
Row 6:	Shows a value collected in 1 unit, but converted to selected standard unit.
Row 9:	Shows use of LBSTNRC for Cannabinoids that is not reported as a continuous numeric result. The result was evaluated by the investigator and determined to be clinically significant
