| Chapter | Genitourinary system diseases/Renal failure |
| Definition | Measurement of serum creatinine in primary care. Values of zero are discarded. The distribution of measurements with units recorded as mmol/L, mol/L or umol/L are all consistent with being recorded in micromol/L. Hence we assume the units are micromol/L regardless of the actual units stated. |

| Implementation | IF enttype = 165 [Serum creatinine] or enttype = 288 [Other laboratory tests] AND Read code in crea_gprd codelist AND data1 [Operator] = 3 ["="] AND data2 [Value] > 0 THEN crea_gprd = data2 |
