Commercial testing companies follow different standards when determining marker values. The SMGF
Search Page automatically converts marker values when you
select a lab. However, we provide the following chart for comparisons between testing companies
and the NIST standard. Some testing companies recently adopted the NIST standard.
Contact your testing company to find out if these changes apply to your results.

Example: If your Genebase DNA test results show DYS442=12, then you would add five to get the NIST equivalent (DYS442=17).

Note: Differences in standards are due to different methods of counting STR values.
