You have to look at the reference range stated on the report as to what determines is negative or positive. Each manufacturer reacts differently and they each can have their own cutoff values. The values are not interchangeable or transferable to other manufacturers test kits.
In general most manufacturers have a value of 1.0 S/C or less as negative. Positives are in the 5.0 or higher S/C values. Those in between are considered indeterminate.
