RESUMO
Objective To establish the reference intervals of 20 dry biochemical items in different age periods among healthy population in Chengdu to providing better support and service for clinical diagnosis and treatment .Methods The stratified random‐ized cluster method was used to collect healthy children and adults in 4 age periods(1 month-3 years old ,>3-7 years old ,>7-18 years old and >18 years old) .Totally 1 495 healthy people (740 males and 755 female) were screened out as the research sub‐jects by the questionnaire ,physical examination and laboratory screening .Fasting venous blood samples were collected from these cases ,then the VITROS 5600 dry biochemistry analyzer was used to detect 20 biochemical items .The obtained results were statisti‐cally analyzed .Results In different groups according to sex and age ,except the conjugated bilirubin (BC) was constant 0 μmol/L , the other items had statistical differences (P<0 .05) .After merging the different groups without statistically significant difference , the obtained reference intervals had significant differences compared with the reference intervals provided by the manufacturer .Con‐clusion Laboratory should establish the different reference intervals aiming at different age and gender populations according to the special character of hospital visiting populations in order to meet the clinical requirements .
