|---|---|---|---|
| ASHA | Arsenic, Hair | Yes | Yes |
| PBHA | Lead, Hair | Yes | Yes |
| HGHAR | Mercury, Hair | Yes | Yes |

Specimen Type Describes the specimen type needed for testing
Hair
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.
Specimen Volume: 0.5 g
Collection Instructions:
1. Prepare and transport specimen per the instructions in the Hair and Nails Collection Kit (Supply T565) or see Hair and Nails Instruction Sheet for Metals Testing in Special Instructions.
2. At least 0.5 g of hair. Typically, this is a sample of hair comprised of strands 1-cm long and enough strands to be 0.5 cm in diameter when gathered together.
Additional Information: If known, indicate source of hair (axillary, head, or pubic).
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 g
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected

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 |
|---|---|---|
| Hair | Ambient (preferred) | |
| Frozen | ||
| Refrigerated | ||
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.
ARSENIC
0-15 years: not established
> or =16 years: 0.0-0.9 mcg/g of hair
LEAD
0.0-3.9 mcg/g of hair
Reference values apply to all ages.
MERCURY
0-15 years: not established
> or =16 years: 0.0-0.9 mcg/g of hair
Interpretation Provides information to assist in interpretation of the test results

Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
"See Individual Unit Codes"
Clinical Reference Provides recommendations for further in-depth reading of a clinical nature

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.
Tuesday, Friday; 5 p.m.
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
7 days
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
14 days
Performing Laboratory Location The location of the laboratory that performs the test
Rochester
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.
This test was developed and its performance characteristics determined by Mayo Clinic in a manner consistent with CLIA requirements. This test has not been cleared or approved by the U.S. 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.
