LABORATORY REFERENCE RANGES
Ranges below are the approximate 95% confidence limits for laboratory reference
values in healthy adult males and females.
Test results can vary depending on measurement conditions and the laboratory
methods utilized.
Therefore, always interpret results using the local testing laboratory’s quoted
reference ranges.
Seek senior doctor adv ice if in doubt.HAEMATOLOGY
