Both SDTM findings class and ADaM BDS class are used to present the results of a test. In SDTM, we present the result using --STRESC or --STRESN variables, while in ADaM we present the results using AVAL and AVALC variable. As per ADaM standard, the value used in PARAMCD for a test should uniquely qualify the result stored in AVAL or AVALC (that is, no additional qualifiers are needed to explain the test). Whereas in SDTM, we can have additional qualifier variables to the --TESTCD variables to understand the test performed. Example 1: If systolic blood pressure is collected in sitting and standing positions for a subject, we use the value of "SYSBP" in VSTESTCD and use VSPOS qualifier to indicate "SITTING" or "STANDING" position of the subject. Here, VSPOS is qualifying the VSTESTCD variable for the result stored in VSSTRESN or VSSTRESC. As we cannot have any additional qualifiers for PARAMCD variable value, we combine the information of qualifier variables and TESTCD value to create a unique PARAMCD value. In this example, a paramcd value of SISBP can be used to indicate the sitting systolic blood pressure and STSBP can be used to indicate the standing systolic blood pressure.
