Test Id : FHEX
Hexagonal Phase Phospholipid (HPP)
Reflex Tests
Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.
| Test Id | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| FHEXN | Comment | No | No |
| FHEXP | Comment | No | No |
Testing Algorithm
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If the hexagonal phase phospholipid result is less than or equal to 8, a negative comment is added. If the hexagonal phase phospholipid result is greater than 8, a positive comment is added.
Method Name
A short description of the method used to perform the test
Clotting time using an activated partial thromboplastin time (aPTT) reagent is determined both in the presence and absence of HPP.
NY State Available
Indicates the status of NY State approval and if the test is orderable for NY State clients.
Reporting Name
Lists a shorter or abbreviated version of the Published Name for a test
Testing Algorithm
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If the hexagonal phase phospholipid result is less than or equal to 8, a negative comment is added. If the hexagonal phase phospholipid result is greater than 8, a positive comment is added.
Specimen Type
Describes the specimen type validated for testing
Plasma Na Cit
Necessary Information
If the patient’s hematocrit exceeds 55%, the volume of citrate in the collection tube must be adjusted.
Specimen Required
Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Patient Preparation: Ideally, the patient should not be on anticoagulant therapy. Avoid warfarin (Coumadin) therapy for two weeks prior to the test and heparin, direct Xa, and thrombin inhibitor therapies for about three days prior to testing. Do not draw from an arm with a heparin lock or heparinized catheter.
Specimen Type: Citrated plasma
Collection Container/Tube: Light-blue top (3.2% sodium citrate)
Submission Container/Tube: Plastic vial
Specimen Volume: 1 mL Plasma
Collection Instructions:
1. Draw blood in a blue-top tube containing 3.2% buffered sodium citrate.
2. Mix immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood.
3. Centrifuge for 10 minutes and remove 2/3 of the plasma using a plastic transfer pipette, being careful not to disturb the cells.
4. Transfer to a plastic transport tube, cap, and centrifuge again for 10 minutes.
5. Use a second plastic pipette to remove the plasma, staying clear of the platelets at the bottom of the tube.
6. Transfer the plasma into a plastic vial and freeze immediately.
7. Send frozen.
Note: Critical frozen. Separate specimens must be submitted when multiple tests are ordered.
Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the testing laboratory. The minimum volume is sufficient for one attempt at testing.
Plasma: 1 mL
Reject Due To
Identifies specimen types and conditions that may cause the specimen to be rejected
| Gross hemolysis | Reject |
| Clotted specimens | Reject |
| Specimen diluted with IV fluids | Reject |
Specimen Stability Information
Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included
| Specimen Type | Temperature | Time | Special Container |
|---|---|---|---|
| Plasma Na Cit | Frozen | 28 days |
Testing Algorithm
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If the hexagonal phase phospholipid result is less than or equal to 8, a negative comment is added. If the hexagonal phase phospholipid result is greater than 8, a positive comment is added.
Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

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.
0-8 sec
PDF Report
Indicates whether the report includes an additional document with charts, images or other enriched information
Day(s) Performed
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.
Monday through Sunday
Report Available
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.
Performing Laboratory Location
Indicates the location of the laboratory that performs the test
