5%; reference interval
, 47%-60%), (40) mild leukopenia in 3 birds (range, 3.
3) The reference interval
was calculated as the range between the 2.
Macroprolactin assessment was performed by PEG precipitation in serum samples with prolactin levels exceeding the normal reference interval
Keep in mind that children are not small adults and that to generate a reference interval
(reference range, normal range) on them would be at least daunting, if not impossible.
Laboratory test results are commonly compared to a reference interval
before caregivers make physiological assessments, medical diagnoses, or management decisions.
A measured or observed laboratory test result from a person (usually a patient) is compared with a reference interval
for the purpose of making a medical diagnosis, therapeutic management decision, or other physiological assessment.

Further testing revealed a low estradiol concentration (20 pg/mL, reference interval
, 24-706 pg/mL), as well as increased total testosterone [96 ng/dL (DPC, Siemens, Malvern PA), reference interval
, 10-80ng/dL] anddehydroepiandrosterone-S (DHEA-S) (594 [micro]g/dL, reference interval
, <340 [micro]g/ dL) (Table 1).
In addition, a reference interval
for the CD4 percentage of lymphocytes needed to be established.
This value is within the reference interval
for Swedish males, 131-163 g/L (3).
Similarly, if an analyte concentration at time 1 hour was truly outside the reference interval
but then shifted to within the reference interval
because of delay in analysis, clinicians might miss important clues about the animal's health.
It is acceptable to use a manufacturer's reference interval
or a reference interval
from another lab using a similar analytical system.
