21004

MAG Antibody, Dual ELISA (Serum)

Two separate ELISAs are performed in order to maximize detection of IgM antibodies recognizing myelin-associated glycoprotein (MAG). One ELISA utilizes purified MAG as antigen, whereas the other utilizes sulfated gluconic acid paragloboside (SGPG), an acidic glycolipid crossreactive with the MAG molecule. Some MAG-specific antibodies react in only one of these ELISAs, whereas others react in both ELISAs. Detection of MAG antibodies is associated with sensorimotor neuropathies. Markedly elevated levels are seen predominantly in demyelinating sensorimotor neuropathies, whereas moderately elevated levels have been reported in multiple sclerosis, inflammatory neuropathies, and motor neuron disease. Approximately 50% of patients with IgM monoclonal gammopathies and associated peripheral neuropathy have detectable MAG antibodies.

This test is approved for New York patient testing.

40675

Measles (Rubeola) IgG and IgM Antibody Panel, IFA (Serum)

The traditional serologic diagnosis of measles requires a significant rise in antibody titer between acute and convalescent sera. However, the diagnosis can also be supported by demonstrating the presence of IgM antibody in a single specimen. Correct interpretation of serologic data depends upon the proper timing of specimen collection in relation to rash onset. This timing is particularly important for interpreting negative IgM results, since IgM antibody peaks approximately 10 days after exposure and may be undetectable 30 days after rash onset. Asymptomatic reinfection can occur in persons who have previously developed antibodies, whether from vaccination or from natural disease. Symptomatic reinfections are rare. These reinfections have been accompanied by rises in measles antibody IgG titers.

This test is available for New York patient testing.

Methodology		IFA (Immunofluorescence Assay)
Reference Range		IgG <1:8 IgM <1:20
Preferred Specimen		1 mL serum (minimum 0.075 mL)
Transport Temperature		2-8° C
Results Available		1 to 4 days

Mycoplasma pneumoniae Culture

Mycoplasma pneumoniae is one of the most common causes of atypical pneumonia, particularly among older children, adolescents, and young adults. Mycoplasma pneumoniae may be recovered from both upper and lower respiratory tract specimens. The organism may be recovered from these specimens throughout the course of the illness and for some time after symptomatic recovery. Because of the fastidious nature of this organism, transport media should be inoculated and sent to the laboratory as quickly after specimen collection as possible. Cultures are held for up to 4 weeks. Culture includes isolation and identification of M. pneumoniae.

This test is approved for New York patient testing.

This test uses highly selective and differential chromogenic medium for isolation of MRSA within 24-36 hours of specimen receipt. This test is a surveillance culture screen only and is not designed to detect infections with MRSA or any other organism.

This test is approved for New York patient testing.

Microsporidia Detection, LM

Microsporidia are obligate intracellular spore-forming protozoa, which are recognized as human pathogens. One microsporidia species, Enterocytozoon bieneusi, has gained attention as an important cause of chronic diarrhea in patients with HIV infection. The estimated prevalence may be as high as 10% in AIDS patients. This diagnostic technique serves as a practical, noninvasive means to detect microsporidia spores in stool specimens and duodenal aspirates.

This test is approved for New York patient testing.

Myelin Basic Protein

Markedly elevated levels of MBP are seen in active demyelinating states such as MS, SSPE or radiation damage. MBP levels are not specific for any disease process but acute exacerbation of MS is indicated by elevated MBP. Moderately elevated levels of MBP are seen in numerous disease states including chronic MS, SSPE myelitis, chemotherapy, central neuritis and radiation.

Myeloperoxidase Antibody

Antibody to myeloperoxidase (MPO) is associated with organ limited vasculitis, including necrotizing and crescentic glomerulonephritis. This assay is useful in confirming MPO specific antibodies in sera which are positive for anti-neutrophil cytoplasmic antibodies of the perinuclear type. Typically the level of MPO antibody parallels disease activities, where increasing disease activity is associated with increasing MPO antibody levels.

This test is approved for New York patient testing.
