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 |
|---|---|---|---|
| HBAG | HBs Antigen, S | Yes | Yes |
| CORAB | HBc Total Ab, w/Reflex, S | Yes | Yes |
| HBAB | HBs Antibody, S | Yes | Yes |
| HAVAB | Hepatitis A Total Ab, w/Reflex, S | Yes | Yes |
Reflex Tests
Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| HBGNT | HBs Antigen Confirmation, S | No | No |
| HAVM | Hepatitis A IgM Ab, S | Yes | No |
| HBIM | HBc IgM Ab, S | Yes | No |
Testing Algorithm
Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Confirmatory testing will be performed at an extra charge on all reactive Hepatitis B Surface Antigen prenatal specimens as well as all other reactive specimens that have a signal-to-cutoff ratio ( S/CO) of < or =50.0. Specimens with an S/CO of >50.0 that are not prenatal specimens do not require confirmation.
If hepatitis Bc antibody total is positive, then hepatitis Bc antibody IgM is performed at an additional charge. If hepatitis A antibody total is positive, then hepatitis A antibody IgM is performed at an additional charge.
Special Instructions and Forms
Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test
Method Name
A short description of the method used to perform the test
Chemiluminescence Immunoassay (CIA)
Reporting Name
A shorter/abbreviated version of the Published Name for a test; an abbreviated test name
Aliases
Lists additional common names for a test, as an aid in searching
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.
Collection Container/Tube: Red top or serum gel
Submission Container/Tube: Plastic vial
Specimen Volume: 3 mL
Collection Instructions: Spin down and remove serum from clot within 24 hours.
Additional Information: Date of draw 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.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Hepatitis A
Hepatitis A virus (HAV) is endemic throughout the world, occurring most commonly, however, in areas of poor hygiene and low socioeconomic conditions. The virus, which is transmitted primarily by the fecal-oral route, is spread by close person-to-person contact and by food- and water-borne epidemics. Outbreaks frequently occur in overcrowded situations and in high-density institutions and centers, such as prisons and health care or day care centers. Viral spread by parenteral contact (with blood or oropharyngeal secretions) is possible but rare, because infected individuals are viremic for a short period of time (usually less than 3 weeks). There is little or no evidence of transplacental transmission from mother to fetus, or of newborns contracting HAV infection during delivery.
Hepatitis B
Hepatitis B virus (HBV) is a DNA virus that is endemic throughout the world. The infection is spread primarily through percutaneous contact with infected blood products, eg, blood transfusion, sharing of needles by drug addicts. The virus is also found in virtually every type of human body fluid and is known to be spread through oral and genital contact. HBV can be transmitted from mother to child during delivery through contact with blood and vaginal secretions; it is not commonly transmitted transplacentally. After a course of acute illness, HBV persists in approximately 10% of patients; some of these chronic carriers are asymptomatic.

Interpretation
Provides information to assist in interpretation of the test results
Hepatitis A virus (HAV) infection
Anti-HAV is usually almost detectable by the onset of symptoms (15-45 days after exposure). Serological diagnosis of acute viral hepatitis A depends on the detection of IgM antibody and its presence indicates recent exposure and the possibility to be potentially infectious. Anti-HAV IgG rises quickly once the virus is cleared and persists for years. A positive anti-HAV (IgG and IgM) indicates that the patient has had either a recent or past HAV infection.
Hepatitis B virus (HBV) infection
Hepatitis B surface antigen (HBsAg) is the first serological marker present following HBV infection. A positive result is diagnostic of acute or chronic hepatitis B infection and is associated with infectivity. Hepatitis B surface antibody (anti-HBs) appears with the resolution of HBV infection after the disappearance of HBsAg. In acute cases, HBsAg usually disappears 1 to 2 months following the onset of symptoms. Persistence of HBsAg for more than 6 months indicates development of either a chronic carrier state or chronic liver disease.
Hepatitis B core antibody (anti-HBc) IgM can be detected in serum shortly after the onset of symptoms and is usually present up to 6 months (ie, core window period). Anti-HBc IgM may be the only serologic marker of a recent hepatitis B infection detectable following the disappearance of HBsAg and prior to the appearance of anti-HBs.
See Viral Hepatitis Serologic Profiles in Special Instructions.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
Positive hepatitis B surface antigen (HBsAg) test results should be reported by the attending physician to the State Department of Health, as required by law in some states.
A weakly positive anti-HBc test result unaccompanied by other hepatitis B serologic markers, elevated liver enzymes, or a history of risk factors may be a false-positive result.
Passively acquired anti-HBs (ie, transfusion, recent immune globulin treatment, etc) does not signify immunity.
Anti-HBs may fall below detectable levels with time.
Performance characteristics have not been established for heat inactivated specimens or specimen containing particulate matter.

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, 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.
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
