biological variability

biological variability

The natural variability in a lab parameter due to physiologic differences among subjects and within the same subject over time.

Types of Biological Variability
• Interindividual—Differences between subjects due to differences in diet, genetics or immune status.
• Intra-individual—Differences in the same subject over time due to diurnal cycles and other rhythms, biological repair mechanisms, dietary variables, ageing, etc.
