Test ID: FFTRP    
Trofile Co-Receptor Tropism Assay

Available on the App Store

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

Co-receptor tropism is defined as an interaction of a virus with

a specific co-receptor on the target cell. To gain entry into

CD4+ cells, HIV must bind to the cell surface CD4 receptor and

to one of two co-receptors, CCR5 or CXCR4.

 

Trofile is a cell-based approach to determine a patient’s

 HIV co-receptor tropism (or “Tropotypeâ„¢). Trofile uses the

complete gp160 coding region of the HIV-1 envelope protein

ensuring that all of the determinants of tropism are tested.

CLIA validation experiments demonstrate that Trofile is 100%

sensitive at detecting 0.3% CXCR4-using minor variants.

 

This class of drugs binds to CCR5 and blocks CCR5-mediated

HIV entry into host cells. Trofile is used to determine whether

a CCR5 antagonist may be an appropriate drug for a patient.

Several clinical trails on CCR5 antagonists have demonstrated

the positive and negative predictive value of Trofile in clinical

settings.

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

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.

18 - 21 days

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

22 - 23 days

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

Monogram Biosciences, Inc
