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 changed accordingly.

For example: Hb now of 12.3 g/dL will become Hb of 123 g/L

If your have any concerns and queries regarding this change please contact Claire Whitehead, Haematology Laboratory Manager, at claire.whitehead@cmft.nhs.uk
