ABSTRACT
BACKGROUND:
To establish reference intervals of carbohydrate antigen 19-9(CA 19-9) according to the CLSI CA28-A3 guideline and to evaluate age- and gender-related variations.METHODS:
Serum CA 19-9 values of 10 149 healthy subjects (from 20 years old to 60 years old) were measured from location health checkups. The relationship between CA 19-9 and age was analyzed using Spearman's approach. The reference intervals of CA19-9 were established using Q2.5 and Q97.5 , and the 90% confidence intervals of upper limits were calculated.RESULTS:
The reference intervals of CA 19-9 were 1.98-25.12 U/mL for males (1.97-25.06 U/mL for 20-50 years old and 2.31-26.13 U/mL for 50-60 years old) and 2.36-29.29 U/mL for adult (20-60 years old) females. The upper limit of reference intervals for all individuals was 26.45 U/mL; the level of CA 19-9 is higher in females than males. Carbohydrate antigen (CA) 19-9 is significantly associated with aging in adult males(r = .0930, P < .0001), but not in females (P = .4734).CONCLUSIONS:
Establishing reference intervals for CA19-9 and giving age-related reference intervals of CA19-9 using a big data of healthy adult, we first discovered that CA19-9 tends to increase with age in adult males but not in females.Palabras clave
