Pediatric Specimen Requirements:

0.5 mL blood in a LAVENDER top tube (EDTA); redraw if specimen clotted. Specimen is stable for up to 7 days refrigerated (2 to 8 C). If testing is delayed more than 7 days, store frozen at -10 C or less.

Reference Range:

Comments:

Test performed by immunoassay using Abbott Architect i1000.

Samples for analysis of Cyclosporine should be collected 30 minutes to 1 hour prior to the next dose so that the measured concentration of drug represents trough level. The optimal therapeutic range for a given patient may differ from this suggested range based on the indication for therapy, treatment phase (initiation or maintenance), use in combination with other drugs, time of specimen collection relative to prior dose, type of transplanted organ, and/or the therapeutic approach of the transplant center.

Reference Range:

Negative.

Index available by report.

Comments:

This test has not been evaluated in neonates and reference ranges have not been established for this age group.

Negative results do not exclude the diagnosis of invasive Aspergillosis.

False negative results may be seen in patients receiving concomitant anti-fungals, and patients with chronic granulomatous disease and Jobs syndrome.

A single positive test result (index equal to or greater than 0.5) should be clinically correlated by testing a separate serum because many agents (e.g. food, antibiotics) may cross-react with the assay. False positive results may also be seen in very young children, patients with altered intestinal barrier, and patients infected with other genre of fungi such as Penicillium, Alternaria, Histoplasma, and Geotrichum.

If invasive Aspergillosis is suspected in high-risk patients, serial sampling is recommended.

Synonyms:

Aspergillus Galactomannan Antigen
