RED CELL FOLATE (RCF)
RCF (nmol/L) = folate result from RCF machine x 31 x 100
There is no consensus on the epidemiological cut off reference values for measuring RCF in the blood. As such, no cut off points have been defined in the NATSIHMS.
Further information about the analysis method and machines used to measure RCF levels is available in Excel spreadsheet format in the Downloads page of this product.

Comparability with other surveys
The NATSIHMS is the first ABS Aboriginal and Torres Strait Islander survey to collect biomedical information. Given it was also the first national level survey (ABS or otherwise) to collect such data for the Aboriginal and Torres Strait Islander population, no comparisons with previous surveys for this population are possible.
However, biomedical data was also collected for all Australians in the 2011-12 National Health Measures Survey (NHMS) and information about comparisons between the NHMS results and those of non-ABS surveys is available from the Comparisons with other Australian surveys section of the Biomedical Results for Chronic Diseases, 2011-12 publication.
