Hba1C O_MM
Hba1C measurement taken at 0 minutes in mmol (IFCC output). Participants will either have Hba1C0_MM or Hba1C0_PC depending on when they are tested earlier on in the study the lab measured Hba1C0 in percentage.

Serum TIBC RAW
Serum biomarker TIBC (Total Iron Binding Capacity) measured in umol/L. Raw data; cleaned data provided in variable G_TIBC with x_Threshold and x_Com variables provided for clarification. TIBC measures the blood's capacity to bind iron with transferrin and is measured by drawing blood and measuring the maximum amount of iron that it can carry which indirectly measures transferrin as transferrin is the most dynamic iron carrier. Data provided by an external lab and was measured on the Siemens Dimension RXL autoanalyser using reagents purchased from Siemens. Only measured on 10000+ Fenland volunteers so far as it is not part of the routine set of measurements.

Urine Albumin
Urine Albumin measurement in mg/l. Prior to (date?) the lab was queried for all results of the value 2.5 to ask if in fact the measuremt fell below 2.5. If so a minus sign was added to the value of 2.5 so a value of -2.5 is present. After that date the lab was no longer queried for values of 2.5 and therefore 2.5 can either represent a true value of 2.5 or any value below 2.5.
