WebOct 21, 2024 · 1. INTRODUCTION. Biological variation (BV) refers to variability in measurand concentration or activity around a homeostatic set point (HSP). Variability is a result of innate physiological factors and may or may not exhibit daily, monthly, or seasonal biological rhythms. 1 Fluctuation around HSPs is assumed to be random, and BV is … WebJul 9, 2024 · Reference values are the values expected for a healthy person. They are sometimes called “normal” values. By comparing your test results with reference values, you and your health care provider can see if any of your test results fall outside the range of expected values. Values that are outside expected ranges can provide clues to help ...
