If the data were entered via CRF, check back to the original CRF. If the CRF was transcribed from a lab report, go back to the original lab report.

If instead the data came from the lab in some electronic format, check the original transfer file.

If the collected units are not mg/dL, make sure the conversion was done correctly.

If all of this checks out, and in the opinion of the appropriate data management personnel the value is suspicious, a query to the site/lab should be issued so that the value can be confirmed or changed. Possibly, that's already happened in the normal course of business.

In the meantime, you use the value you have.
