Examples of normal results:
Examples of pathogen detection:

- NEG: pathogen not found in the specimen (No evidence or no growth). Note: Negative does not necessarily imply the complete absence of the specified item.
Examples abnormal results with numeric values:
- H: High - Above reference range
- HH: High alert - Above reference range (critical value)
- L: Low - Below reference range
- LL: Low alert - Below reference range (critical value)
Examples of non-determinable results: - >: High off scale - Above analytical limit
- <: Low off scale - Below analytical limit
Examples of antimicrobial susceptibility tests in microbiology: - S: susceptible
- R: resistant
- I: intermediate
- SDD: Susceptible-dose dependent
