Test ID: ALDEF    
Alpha Defensin, Lateral Flow Assay, Synovial Fluid

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

The Alpha Defensin Lateral Flow Test Kit is an immunoassay test system comprised of a single use device, a premeasured vial of dilution buffer, a disposable Microsafe tube, and a sample cup.

 

Each device contains a reagent strip with all of the critical components for the assay. Dilution is performed by collecting a sample from an aspirated synovial fluid specimen using the disposable Microsafe tube and adding the sample to the premeasured dilution buffer. Three full, free-falling drops of the diluted sample are then added to the test device to begin the testing process. Cellular material is removed by the first pad. The solution then migrates to the buffering pad and mixes with the gold conjugate that has been labelled with an anti-alpha defensin antibody. The test mixture then migrates across the test line and the control line. A test result line will form if the level of alpha defensin in the sample is greater than the cut-off concentration. A control line will form to confirm that the solution has properly flowed across the device. Results can be read between 10 to 20 minutes.(Package insert: Synovasure Alpha Defensin Lateral Flow Test Kit, CD Diagnostics, Inc., Claymont, DE, M40004B V5)

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 Friday, Sunday; 12 p.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.

Same day/1 day

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

7 days

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