CALPROTECTIN - FECAL

LAB3763

Collect

Stool.

Specimen Preparation

Transfer 5 g stool to an unpreserved stool transport vial (ARUP Supply #40910). Available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. (Min: 1 g)

Unacceptable Conditions

Specimens in media or preservatives.

Storage/Transport Temperature

Refrigerated.

Stability (from collection to initiation)

Ambient: 11 days; Refrigerated: 11 days; Frozen: 1 year

Notes

Fecal Calprotectin is an indicator of the presence of neutrophils in stool and is not specific for IBD. Other intestinal ailments including GI infections and colorectal cancer can result in elevated concentrations of calprotectin. The diagnosis of IBD cannot be established solely on the basis of a positive calprotectin result. Patients with IBD fluctuate between active and inactive stages of disease. Calprotectin results may also fluctuate. GI bleeding of as much as 100 mL per day will increase the fecal calprotectin concentration by only 15 µg/g.

Ordering Recommendations

Monitor therapy and identify disease recurrence in individuals with metastatic breast cancer. Do not use for diagnosis or screening of breast cancer.

Reference Interval

0-31 U/mL

Interpretive Data

The Roche CA 15-3 electrochemiluminescent immunoassay is used. Results obtained with different methods or kits cannot be used interchangeably. The CA 15-3 test is used to aid in the management of Stage II and III breast cancer patients. Serial testing for patient CA 15-3 values should be used in conjunction with other clinical methods for monitoring breast cancer. Patients with confirmed breast carcinoma frequently have CA 15-3 values in the same range as healthy individuals. Elevations may be observed in patients with nonmalignant disease. Therefore, a CA 15-3 value, regardless of level, should not be interpreted as absolute evidence of the presence or absence of malignant disease.

Interpretive Data

Serum from healthy individuals and patients with mucocutaneous candidiasis generally does not have positive immunodiffusion tests. Approximately 88% of immunologically competent patients with visceral candidiasis will demonstrate one or more precipitin bands. Two to nine bands have been associated with serum from patients with systemic infections. Generally, the greater the number of bands, the more severe the infection (except with immunocompromised patients).
