How to select tests and population

The left side panel contains a number of options for selecting tests and the population of interest for the research project.

Test characteristics

  • Test type: The list includes all tests in the CopLab database that have been mapped according to IUPAC's standards.

  • Test requester: The tests in CopLab were mostly requested by general practitioners (GP). However, some were requested by other private practicing specialists (non GP).

  • Year of test: Calendar year for the date of the test.

Population characteristics

  • Age at test: Age of the person at the date of the test.

  • Sex: Sex of the person.

Summaries for the selected population

The right side contains tabs with different summaries of the selected population. Some counts are under-approximations, since rare combinations are 'blinded' to avoid identification of individuals. The total number of tests are likely larger than the number of individuals, since some individuals may have multiple tests. When reporting the results back to the requester, the laboratory indicated whether the test result was below or above a reference level. The thresholds for the reference level changed for some tests over time.

  • Overview of tests: A table with the number of tests for each selected test. The table contains the total number of tests and how many of those that were considered above or below reference.

  • Tests by year: Figures that show the number of tests by calendar year for each selected test. The colors indicate whether the laboratory reported the tests as being normal, below or above reference.


The purpose of this website is to make it quick and easy for researchers to assess how much data that are potentially available in the CopLab database when considering a new research project.
