SI Units of Medical Laboratory

Unit:

The S.I unit is derived from “system international d’’ According to recommendation of WHO , S .I units are used in the laboratory in following ways:
·         In test methods.
·         Preparation of reagent.
·         Reporting of test result
The international system of units has been developed and agreed internationally. It overcomes language berried , enabling an exchange of health information  within a country and between nation to unmade the misunderstanding . It is therefore important for health authorities to adopts S,I unit as far as possible.
The international system of units based on the mete-kilogram- second system and replaces both the foot –pound –second (FPS) system and the centimeter-gram=second (CGS) system .The following units are called S.I base unit because all other S.I units are derived from these units.
