Additionally, some preliminary results suggest that the upper reference limits for healthy newborns are higher than those for adults but definitive reference limits for newborns are not available.
Confidence interval and sample size procedures are available for studying regression-based reference limits.
Reference limits are widely used in anthropometry, the behavioral sciences, medicine, and clinical chemistry.
We established population-based reference limits for plasma total homocysteine (tHcy) according to creatinine.
Thus, instead of estimating reference limits separately for several age groups, it is more economical and parsimonious to use regression methods to estimate reference limits as a function of age.
Ref. Val. = maximum reference limits for human consumption, MPN = most probable number, CFU = colony-forming units, Abs.
For the geriatric population, upper reference limits (URLs) for alanine aminotransferase (ALT) levels have not been established.
TSH, CRP, Sedimentation rate (SR), s-electrophoresis and transferrin saturation were all within reference limits (Table 2).
Peripheral blood profiles were within reference limits.
Lower reference limits for anemia and Cbl deficiency were defined according to Danish reference limits.
Prostate safety parameters are well within reference limits.
