Reference Ranges
Reference Ranges are the normal values or acceptable ranges used in medical testing and diagnostics to determine if test results are normal or abnormal. Think of them like a "healthy zone" on a measurement scale. Just like how a normal body temperature is between 97-99°F, every medical test has its own reference range. These ranges help healthcare workers decide if patient results are concerning or perfectly fine. Different labs might have slightly different ranges based on their equipment and the populations they serve. When you see this term on a resume, it usually means the person has experience working with laboratory results, quality control, or setting up testing procedures.
