How to calculate the geometric mean titer (GMT) of titers from a haemagglutination assay (influenza)?
Typically "<10" is converted to a number that is below the limit of detection; often "9". After that simply following the instructions you have yields a GMT of 77.9. If you are using spreadsheet apps such as Excel or Google Sheets, they almost certainly offer "GEOMEAN" functions which will give the number directly.
