Test ID: FENT
Enterovirus Panel II, CF (Serum)
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.
Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| CXA_1 | Coxsackie A Antibodies, S | Yes, (order COXA) | Yes |
| CXB_2 | Coxsackie B(1-6) Antibodies, Serum | Yes, (order COXB) | Yes |
| ECH_2 | Echovirus Antibodies, S | Yes, (order ECHO) | Yes |
| POL_1 | Poliovirus (Types 1-3) Antibody, S | Yes, (order POLIO) | Yes |

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.
Draw blood in plain, red-top tube(s). (Serum gel tube is
acceptable.) Spin down and send 3 mL serum, refrigerated.
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
| Specimens other than | Serum |
| Anticoagulants other than | NA |
| Hemolysis | NA |
| Thawing | Warm OK; Cold OK |
| 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 |
|---|---|---|
| Serum | Refrigerated (preferred) | 14 days |
| Frozen | 30 days | |
| Ambient | 7 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.
Reference Range: < 1:8
INTERPRETIVE CRITERIA for Coxsackie A, B and Echovirus:
< 1:8 Antibody Not Detected
> or = 1:8 Antibody Detected
Single titers > or = 1:32 are indicative of recent infection. Titers of
1:8 and 1:16 may be indicative of either past or recent infection,
since CF antibody levels persist for only a few months. A four-fold
or greater increase in titer between acute and convalescent
specimens confirms the diagnosis. There is considerable
crossreactivity among enteroviruses; however, the highest titer
is usually associated with the infecting serotype.
INTERPRETIVE CRITERIA for Poliovirus:
< 1:8 Antibody Not Detected
> or = 1:8 Antibody Detected
Because CF antibody levels usually persist for only a few months,
any measurable titer may indicate recent exposure. Single titers
> or = 1:32 provide strong evidence for recent exposure. A four-fold
or greater increase in titer between acute and convalescent specimens
confirms recent exposure or infection.

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 Friday
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
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location The location of the laboratory that performs the test
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.
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.
