181Diagnostic use in the quantitative determination of prolactin in serum.
|Methodology:||Quantitative Chemiluminescent Immunoassay|
Collect: Serum Separator Tube (SST)
Specimen Preparation: Allow blood samples to clot (15 mins). Separate the serum from the cells by centrifuging for 10 minutes. Store serum at 2-8°C until analysis.
Storage/Transport Temperature: Refrigerated
Stability: Tightly cap and refrigerate specimens at 2 to 8°C if the assay is not completed within 8 hours. Freeze samples at or below -20°C if the sample is not assayed within 48 hours.
NOTE: * This test is approved for all states. *

|Cross Reference:||Prolactin, Dilution Study (Prolactin)|
Expected Results The expected results for the Prolactin assay were previously established. Data was obtained on serum samples from 661 apparently healthy individuals. Based on a central 95% interval, the following reference ranges were established:
Category N Mean (ng/mL) Range (ng/mL) Mean (µIU/mL) Range (µIU/mL)
202 9.6 2.8–29.2 204 59–619
216 61.7 9.7–208.5 1308 206–4420
104 6.9 1.8–20.3 146 38–430
139 7.0 2.1–17.7 148 45–375
These results were confirmed for the Prolactin assay by analyzing 279 samples in the range of 1.4 to 185.1 ng/mL (29.3 to 3925.0 μIU/mL).
0.3 – 200 ng/mL.
Values greater than 200 ng/mL will be reported as >200 ng/mL
LIMITATIONS: Pregnancy, lactation, and the administration of oral contraceptives can increase prolactin concentrations. .
