Survey on range or reference value of alanine aminotransferase( ALT) of health blood donation crowd in Handan
Objective To survey on range of reference value of alanine aminotransferase(ALT) of health blood donation crowd in Handan. Methods To take the rate method to detect ALT value of 18~55 years old 10844 of health blood donors from 2010 1~2 months in Handan. The results were statistically analysised. Results ALT levels were log-normal distribution. The reference value range of 95% health donors was less than 51. 7 U/L in this area. Among them,the male was 7512 cases,female was 3332 cases. The geometric mean differences were 21. 5 U/L, 13. 8 U/L,so that men and women had difference(F<0. 0001),and men were higher than women,95% reference value of ALT less than 57.1 and 34.3 U/L. Each age group, the ALT of 18~ year old was lower than any other age group(5 years old interval a group,and the last group of 48~55 years old),geometric mean differences among all age groups respectively :14. 9,17. 9,20. 9,20. 4,20. 4,18. 8,19. 6 U/ L,95% reference value range of donors were less than:40.1, 51.0,58. 9,52. 8,55. 1,50. 7,44. 9 U/L. Conclusions The survey reflects the ALT average level of the health of blood donation crowd in Handan area,95% reference value range of male is greater than 40 U/L(the national standard),women's 95% reference value range is lower than the state provisions 40 U/L standards; ALT value in every age group, 95% reference value range are more then 40 U/L, 18~the minimum age group. This can be for related department reference.
