Which term describes quantitative testing information?

• A. Presence/absence testing
• B. Strength, concentration
• C. Substance identification
• D. Sterility

Answer: (B)

Quantitative testing provides numerical measurements of how much active drug is present, not just a yes/no result. In compounding, you want to know the exact potency or content per unit, which is captured by strength or concentration. For example, reporting a product as having a potency of 98% or a concentration of 5 mg/mL gives a specific amount, enabling precise dosing and quality control. The other terms describe qualitative information. Presence/absence testing answers whether something is detectable at all, a binary result rather than a quantity. Substance identification confirms what the substance is, again a qualitative determination. Sterility indicates whether microbial contamination is present, typically a pass/fail result rather than a numeric value.
