Test ID: FLUPV
Lupus Anticoagulant Evaluation w/Reflexes
Secondary ID 
A test code used for billing and in test definitions created prior to November 2011
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| FHEXC | Hexagonal Phase Confirm | No | No |
| FDVTC | DRVVT Confirm | No | No |
| FDVTX | DRVVT 1:1 Mix | No | No |
| FCLOT | Thrombin Clotting Time | No | No |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
If the PTT-LA is >40, then the Hexagonal Phase Confirmation (FHEXC) will be performed at an additional charge.
If the Hexagonal Phase Confirm is positive or weakly positive, a Thrombin Clotting Time (FCLOT) will be performed at an additional charge.
If the DRVVT Screen is >45 then the DRVVT Confirmation (FDVTC) will be performed at an additional charge.
If the DRVVT Confirmation is positive, then the DRVVT 1:1 Mix (FDVTX) will be performed at an additional charge.

Specimen Type Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
3 mL platelet-poor plasma, shipped frozen. Draw blood into a 3.2% sodium citrate (light blue-top) tube. Mix gently by inverting 3-4 times. Centrifuge 15 minutes at 2500-3500 RPM. Using a plastic pipette, remove plasma, taking care to avoid the WBC/platelet buffy layer and place into plastic vial. Centrifuge a second time and, using a plastic pipette, transfer platelet-poor plasma into a new plastic vial. Plasma must be free of platelets (<10,000/uL).
Freeze immediately.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| Hemolysis | NA |
| Thawing | Warm reject; Cold reject |
| Lipemia | NA |
| Icteric | NA |
| Other | NA |
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
| Specimen Type | Temperature | Time |
|---|---|---|
| Plasma Na Cit | Frozen | 90 days |
Reference Values 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.
Lupus Anticoagulant Not Detected
This interpretation is based on the
following test results:
PTT-LA Screen < or =40 seconds
Test Performed by: Quest Diagnostics Nichols Institute
33608 Ortega Highway
San Juan Capistrano, CA 92690-6130
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
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.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Performing Laboratory Location The location of the laboratory that performs the test
CPT Code Information Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Medical Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.

85670/Thrombin Clotting Time (if appropriate)
LOINC® Code Information Provides guidance in determining the Logical Observation Identifiers Names and Codes (LOINC) values for the result codes returned for this test or profile.
| Result ID | Reporting Name | LOINC Code |
|---|---|---|
