OBJECTIVES: To predict duration of azotemia and distinguish acute renal failure clinically from chronic renal failure by measuring the concentration of hair creatinine and analysing the correlation between Hcr and serum creatinine in 59 patients with acute renal failure and 64 patients with chronic renal failure .

目的：通过对59例急性肾功能衰竭(Acute renal failure，ARF)病人和64例慢性肾功能衰竭(Chronic renal failure，CRF)病人头发肌酐含量(Hair creatinine concentration，Hcr)测定、比较ARF组和CRF组病人就诊时30-40mm段头发肌酐含量之间的差别、对Hcr与血肌酐浓度(Serum creatinine，Scr)相关关系的研究，在临床上利用头发肌酐含量测定来判定肾功能衰竭持续的时间，进一步鉴别急、慢性肾功能衰竭。
