Regarding the comments for items 502 and 504 this is feedback I received from the medical technical people:

Qualitative - Positive or negative results. Presence or absence of an analyte. Showing a degree of reactivity. Quantitative - Usually seen in chemistry, hematology or coagulation results. Semi-quantitative - Yielding an approximation of the quantity or amount of a substance; between a qualitative and quantitative result.


 * Ballot comment #504. Below are 2 descriptions that address common expressions of ratios. As you can see a ratio may be expressed as a whole number (NM). I recommend in Table 3-12 that the OBX.2 field for Numerical intervals, ratios, inequalities be shown as SN, NM. **
 * The ratio of 6 to 3 should be stated as 2 to 1, but common usage has shortened the expression of ratios to be called simply 2. **
