Reference ranges are usually given as what are the usual (or normal) values found in the population, more specifically the prediction interval that 95% of the population fall into. Arterial levels for drugs are generally higher than venous levels because of extraction while passing through tissues. Still, the blood values are approximately equal between the arterial and venous sides for most substances, with the exception of acid–base, blood gases and drugs (used in therapeutic drug monitoring (TDM) assays). An exception is for acid–base and blood gases, which are generally given for arterial blood. If not otherwise specified, a reference range for a blood test is generally the venous range, as the standard process of obtaining a sample is by venipuncture. for beta cell function in homeostasis model assessment or thyroid's secretory capacity. Percentages and time-dependent units (mol/s) are used for calculated derived parameters, e.g.liver function tests like AST, ALT, LD and γ-GT in Sweden. Enzyme activity ( kat) is commonly used for e.g.International units (IU) are based on measured biological activity or effect, or for some substances, a specified equivalent mass.Molar concentration (mol/L) is used to a higher degree in most of the rest of the world, including the United Kingdom and other parts of Europe and Australia and New Zealand.Is usually given with dL (decilitres) as the denominator in the United States, and usually with L (litres) in, for example, Sweden.
