91554
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
No
Method Name A short description of the method used to perform the test
Ultraviolet Spectrophotometry
Reporting Name A shorter/abbreviated version of the Published Name for a test; an abbreviated test name
Adenosine Deaminase, Fluid
Specimen Type Describes the specimen type needed for testing
Varies
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.
Centrifuge and aliquot 0.3 mL of body fluid. Transfer supernatant to a plastic vial, freeze immediately and ship frozen.
Note:
1. Must be frozen within 24 hours of collection. No freeze/thaw cycles.
2. Date of Birth is Required
3. Source is Required
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.
0.1 mL
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| Specimens other than | Body fluid |
| Anticoagulants other than | NA |
| Hemolysis | Mild reject; Gross reject |
| Thawing | 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 |
|---|---|---|
| Varies | 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.
Pleural Exudate:
Total protein >3.0 g/dL: 1.6-9.2 U/L
Pleural Transudate:
Total protein <3.0 g/dL: 0-6.7 U/L
Peritoneal Exudate:
Total protein >2.0 g/dL: 0-7.6 U/L
Peritoneal Transudate:
Total protein <2.0 g/dL: 0-7.6 U/L
Performance characteristics for specimen types other than pleural or peritoneal are unknown. Reference ranges have not been established.
Test Performed by: University of Minnesota Physicians Outreach Laboratory
420 Delaware St. S.E.
Minneapolis, MN 55455
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.
3 – 5 times per week
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.
2 days
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
5 - 9 days
Performing Laboratory Location The location of the laboratory that performs the test
Univ of Minnesota Outreach Laboratories
Test Classification Provides information regarding the medical device classification for laboratory test kits and reagents. Tests may be classified as cleared or approved by the US Food and Drug Administration (FDA) and used per manufacturer's instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR), Investigation Use Only (IUO) product, or a Research Use Only (RUO) product.
Analyte Specific Reagents (ASRs) are used in many laboratory tests necessary for standard medical care and generally do not require FDA approval. This test was developed and its performance characteristics determined by Fairview University Medical Center Clinical Laboratories. It has not been cleared or approved by the US Food and Drug Administration.
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.
84311
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.
