Routine clinical chemistry and haematological test reference intervals for healthy adults in the Bhutanese population.

Laboratory medicine plays a critical role in the modern healthcare system, and it is reported to influence 60-70% of clinical decision makings. The quantitative laboratory test results are interpreted by comparing to the Reference Intervals (RIs) and therefore the use of appropriate RIs is critical. Clinical laboratories in Bhutan have been randomly using RIs from textbooks and manufacturer's package inserts without even verifying their applicability and therefore lessening their contribution to clinical decision makings.
