Specimen Type Describes the specimen type needed for testing
Whole Blood NaFl-KOx
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.
Draw blood in a grey-top (potassium oxalate/sodium fluoride
tube(s), and send 7 mL of potassium oxalate/sodium fluoride
whole blood refrigerated.
Note: If potassium oxalate/sodium fluoride tube is not used,
freeze immediately and send frozen in plastic vial.
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.
3 mL
Note: Submission of the minimum volume results in an elevated
reporting limit and inability to repeat analysis.
Note: Submission of the minimum volume results in an elevated
reporting limit and inability to repeat analysis.
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| Specimens other than | Whole blood |
| Anticoagulants other than | Potassium oxalate/sodium fluoride, EDTA, sodium heparin |
| Hemolysis | NA |
| Thawing | Potassium oxalate/sodium fluoride – NA EDTA or sodium heparin – Warm reject; Cold reject |
| Lipemia | NA |
| Icteric | 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 |
|---|---|---|
| Whole Blood NaFl-KOx | Refrigerated (preferred) | |
| Ambient | 72 hours | |
| Frozen | ||
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.
Test Performed by: Medtox Laboratories, Inc.
402 W. County Road D
St. Paul, MN 55112
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 Sunday
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.
10 days
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
12 - 13 days
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
2 weeks
Performing Laboratory Location The location of the laboratory that performs the test
