MALES 0.2 - 1.4 ng/ml FEMALES - menstrating: Follicular Phase 0.2 - 1.5 ng/ml Ovulation Phase 0.8 - 3.0 ng/ml Luteal Phase 1.7 - 27.0 ng/ml POSTMENOPAUSAL FEMALES <0.2 - 0.8 ng/ml | ||
Comments: |
New analytical immunoassay with different reference ranges instituted 3/13/00 at 0700. | ||
Test Limitations: |
The assay is unaffected by icterus = 54(bilirubin ditaurate is less than 54 mg/dl), hemolysis = 1000 (Hb is less than 1.0 g/dl), lipemia = 720 (Intralipid is less than 720 mg/dl) and biotin is less than 20 ng/ml. (criterion: recovery within plus or minus 10% of initial value). In patients receiving therapy with high biotin doses (i.e. is greater than 5 mg/day) no sample should be taken until at least 8 hours after the last biotin administration. No interference was observed from rheumatoid factors up to a concentration of 2000 U/ml. In vitro tests were performed on 18 commonly used pharmaceuticals. Of these, only phenylbutazone at therapeutic dosage levels showed interference with the assay (progesterone values depressed). As with all tests containing monoclonal antibodies, erroneous findings may be obtained from samples taken from patients who have been treated with monoclonal mouse antibodies or who have received them for diagnostic purposes. In rare cases, interference due to extremely high titers of antibodies to ruthenium can occur. Progesterone II contains additives which minimize these effects. Extremely high titers of antibodies to streptavidin can occur in isolated cases and cause interference. For diagnostic purposes, the Progesterone II findings should always be assessed in conjunction with the patient's medical history, clinical examination and other findings. | ||
