TEST_OUTCOME

This column provides a label comparing the measured value against a reference range.

Value	Description
N	Normal
A	Abnormal
AA	Very abnormal
L	Low
LL	Very low
H	High
HH	Very high

TEST_OUTCOME_IMPUTED

Some rows are missing the TEST_OUTCOME, so an imputed one is provided. The TEST_OUTCOME_IMPUTED is derived by looking at the data from the same OMOP Concept ID for which there are MEASUREMENT_VALUE and TEST_OUTCOME.

Value	Description
N	Imputed Normal
L	Imputed Low
L*	Imputed Low. Less confidence in the imputation due to over-representation of L and H from TEST_OUTCOME
H	Imputed High
H*	Imputed High. Less confidence in the imputation due to over-representation of L and H from TEST_OUTCOME

MEASUREMENT_STATUS

Value	Description
C	Corrected result
F	Final result
R	Unverified result
S	Partial result

Test name abbreviations

Test name abbreviations come from different laboratory testing centers around Finland. Some are standardized nationally and some are used only locally in different hospitals and test centers.

We have put a lot of effort into standardizing these to international OHDSI OMOP Concept ID (primarily from LOINC) so we hope that you do not need to interpret them very often! However, in case you have reason to use them, we provide the meaning of most abbreviations here.
