Table Description. Medians of the coefficients of inter-individual (med CVBb ) and intra-individual (med CVBw ) biological variation of biological quantities in healthy subjects estimated in different studies with different time spans. [The symbols used in this table are: h = hour; d = day; wk = week; mo = month; a = year; r = mass concentration; b = catalytic concentration ; m = mass; c = substance concentration; n/N= entitic amount of substance; n = amount of substance; p = partial pressure; arb = arbitrary; t = time; C = number concentration; f = volume fraction; V/N= entitic volume; f = volume; x = substance fraction; l = length; z = catalitic activity; NO = no data available]. According to ISO, IUPAC and IFCC recommendations the comma is used as decimal sign.
