"Values and units of measurement listed in these tables are derived from several resources. Substantial variation exists in the ranges quoted as “normal” and may vary depending on the assay used by different laboratories. Therefore, these tables should be considered as directional only. Some values (e.g. hormones) vary by gender, age, time of day and condition (e.g. pregnancy) so a text on endocrinology should be consulted for complete data. Where possible, Canadian sources are used, Globalrph.com was used to provide non SI unit conversions." |
