Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Pantothenic acid, commonly known as vitamin B5, is a water-soluble vitamin. As part of acetyl CoA or an acyl carrier protein, pantothenic acid plays an essential role in metabolic pathways. It functions in the oxidation of both fatty acids and carbohydrates for energy production in the form of A TP. Vitamin B5 also participates in the synthesis of amino acids, fatty acids, ketones, cholesterol, phospholipids, and steroids. Additionally, vitamin B5 contributes to porphyrin and hemoglobin biochemistry and in adrenal function. Pantothenic acid deficiency is exceedingly rare, mostly affecting individuals who are severely malnourished. Those who lack an adequate amount of vitamin B5 may demonstrate symptoms such as paresthesias, muscle weakness, fatigue, nausea, abdominal pains and susceptibility to infection.


Reference Values

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.


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.

4 to 18 days

Performing Laboratory Location
Indicates 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 instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR) product.

The performance characteristics of the listed assay was validated by BioAgilytix Diagnostics. The US FDA has not approved or cleared this test. The results of this assay can be used for clinical diagnosis without FDA approval. BioAgilytix Diagnostics is a CLIA certified,  CAP accredited laboratory for performing high complexity assays such as this one.

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 Clinic Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.

CPT codes are provided by the performing laboratory.


LOINC® Information
Provides guidance in determining the Logical Observation Identifiers Names and Codes (LOINC) values for the order and results codes of this test. LOINC values are provided by the performing laboratory.
