Eff. October 1, 1985.

10A NCAC 42B .0102       CLINICAL CHEMISTRY/NEWBORN SCREENING

(a)  This laboratory will examine specimens for evidence of certain inborn errors of metabolism, for the detection of chronic diseases, diabetes, renal diseases, hypertension, certain clinical chemistry and hematology tests when requested by authorized senders of specimens within the guidelines of the Division of Maternal and Child Health and the Division of Public Health.

(b)  This laboratory performs tests for hemoglobinopathies such as sickle cell trait and disease.

Eff. October 1, 1985;

Amended Eff. September 1, 1990.

 

10A NCAC 42B .0103       ENVIRONMENTAL SCIENCES

(a)  This laboratory examines samples of drinking water and other environmental materials for evidence of microbiological, chemical or other contamination.  No test will be performed on a sample from an open well or an unprotected spring because such supplies are unsafe to drink regardless of laboratory findings.

(b)  This laboratory examines samples for monitoring man‑made and natural radiochemical levels in air, water, soil, animal and vegetable material, milk and other foods.

(c)  This laboratory examines samples of drinking water, samples from industrial environments and other environmental material for the presence of excess levels of inorganic or organic compounds which are deemed detrimental to human health.  Sample containers supplied by this laboratory must be used to collect samples.

10A NCAC 42B .0104       LABORATORY IMPROVEMENT

(a)  Participation in the proficiency testing offered by this laboratory is mandatory for laboratories certified in milk and for laboratories funded through the federal gonorrhea grant to culture females for gonorrhea.  Participation in other proficiency testing or by other laboratories is voluntary.

(b)  Formal training courses in laboratory procedures and laboratory management are presented by this laboratory for health related laboratorians in the state.  Courses are announced in the bulletin, LABORATORY, and are planned in response to requests and needs demonstrated by proficiency testing results.

(c)  The bulletin, LABORATORY, is published quarterly and includes announcements of courses offered and information important to laboratory scientists and managers.  The bulletin is available to any health related laboratory.

10A NCAC 42B .0105       MICROBIOLOGY

(a)  This laboratory isolates and identifies anaerobic organisms and serves as a reference laboratory for confirmation of further identification of anaerobic bacteria.

(b)  The laboratory examines fecal specimens for enteric pathogens from symptomatic patients, typhoid carriers, and contacts of such individuals.  Environmental samples, such as food and water from aquariums or turtle bowls are examined if they are implicated as vehicles of infection.  This laboratory is the designated serotyping center for the state of all isolates of salmonella and shigella for confirmation and surveillance purposes.

(c)  This laboratory isolates and identifies pathogenic fungi from body tissues and fluids and serves as a reference laboratory for confirmation or further identification of fungi.

(d)  This laboratory examines fecal and other specimens from symptomatic patients for the eggs, cysts, and larvae of the intestinal parasitic worms and protozoa.  Blood smears are examined for parasitic blood diseases, such as malaria.  Reference specimens or prepared stained slides from preserved material, biopsy material and tissue aspirates for tissue parasites are also accepted.  Identification of arthropods is made.

(e)  This laboratory accepts a wide variety of bacteria which have been isolated by hospital or other laboratories, which are unusual, difficult to identify, fastidious, or infrequently encountered, thereby serving as a reference laboratory for other laboratories.

(f)  Sputa and specimens from other sources are examined for mycobacteria, including MYCOBATERIUM TUBERCULOSIS and all isolates are tested for drug susceptibility using the drugs most commonly used for treating tuberculosis.

(g)  This laboratory may examine, upon request of an authorized sender of specimens, a variety of other specimens as the public health may require.

10A NCAC 42B .0106       VIROLOGY/SEROLOGY

(a)  The services available for the laboratory diagnosis of viral infections are based on the following general approaches:

(1)           the examination of serum for the demonstration of a significant increase in antibody titer to a given virus;

(2)           the examination of pathological fluids, tissue, and other suitable material for the isolation and identification of the viral agent; and

(3)           the examination of infected tissue to demonstrate the presence of viral material or for changes which are characteristic of a particular viral disease.

(b)  Several types of serological procedures and variations of those are used to study and detect evidence of rickettsial, bacterial, fungal and parasitic diseases as well as viruses.

(c)  Only the head of animals larger than the common gray squirrel shall be accepted.  Gray squirrels and small animals, including bats, shall, when possible, be submitted intact.
