1,3-Beta-D-Glucan (Fungitell), Serum

Method Description Describes how the test is performed and provides a method-specific reference

The Fungitell assay measures levels of (1,3)-beta-D-glucan (BDG). The assay is based upon a modification of the Limulus amebocyte lysate (LAL) pathway. The Fungitell reagent is modified to eliminate factor C and, thus, to only react to BDG, through the factor G-mediated side of the pathway. BDG activates factor G, a serine protease zymogen. The activated factor G converts the inactive proclotting enzyme to the active clotting enzyme, which in turn cleaves pNA from the chromogenic peptide substrate, Boc-Leu-Gly-Arg-pNA, creating a chromophore that absorbs at 405 nm. The Fungitell kinetic assay is based upon the determination of the rate of optical density (OD) increase produced by a sample. This rate is interpreted against a standard curve to produce estimates of BDG concentration in the sample.(Package insert: Assay for [(1,3]-Beta-D-Glucan in Serum, Associates of Cape Cod Inc. 02/2011)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Monday through Saturday; 9 a.m.

Sunday; 7 a.m.

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

2 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

2 weeks/14 days

Performing Laboratory Location Indicates the location of the laboratory that performs the test
