Change to haemoglobin reporting units
There will be a change to the way haemoglobin (Hb) units
are reported from Tuesday, March 12, 2013.
All UK laboratories are required to standardize on g/L for
the units of measurement and reporting of Haemoglobin (Hb) and Mean
Cell Haemoglobin Concentration (MCHC).
The laboratories at Central Manchester and Trafford
Hospitals and all Point of Care instrumentation currently reports
Hb and MCHC in g/dL.
To comply with the national
recommendation we will convert to g/L which requires changing
the units by a factor of x10. Reference ranges will be
For example: Hb now of 12.3 g/dL will become Hb of 123

change please contact Claire Whitehead, Haematology Laboratory
