A short description of the method used to perform the test
CD4 cell culture assay for phenotypic recombinant virus
NY State Available
Indicates the status of NY State approval and if the test is orderable for NY State clients.
Lists a shorter or abbreviated version of the Published Name for a test
Phenosense Entry Fuzeon
Lists additional common names for a test, as an aid in searching
Describes the specimen type validated for testing
Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Draw blood into two 5-mL PPT (pearl top) or EDTA (lavender top) tube. Immediately centrifuge (within 2 hours of collection) at 1000-1200xg at room temperature for 10-15 minutes. Do not allow samples to remain in centrifuge after centrifugation. Remove plasma from cells immediately and transfer to a plastic screw-cap tube. Freeze immediately. Send 3 mL plasma in a screw-cap vial frozen.
1. Patient's most recent viral load
2. Viral load collection date
1. Intended for use only for patients with viral loads greater than or equal to 500 copies/mL. For best results, viral loads should be confirmed within two weeks prior to submission for testing at Monogram.
2. Patient samples submitted <30 days apart are considered duplicate and will be canceled.
Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory
Reject Due To

Specimen Stability Information
Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
A final report will be attached in MayoAccess.
Indicates whether the report includes an additional document with charts, images or other enriched information
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.
14 to 21 days
Performing Laboratory Location
Indicates the location of the laboratory that performs the test
Monogram Biosciences, Inc
