Aspergillus Antigen, EIA, Serum print

Invasive aspergillosis occurs mainly in patients with neutropenia subsequent to anti-cancer therapy and in patients treated aggressively with immunosuppressants (particularly transplant recipients). Detection of Aspergillus antigen (galactomannan) in serum has been shown to be a valuable tool in diagnosing invasive aspergillosis when used in conjunction with other diagnostic tools, including culture, histology of biopsy samples, and radiography. It is recommended that high-risk patients be tested prospectively.

This test is approved for New York patient testing.

Haemophilus influenzae Serotyping (A-F), SA print

Encapsulated Haemophilus influenzae can be separated into 6 capsular serotypes, a-f. Most upper respiratory tract strains of H. influenzae are non-encapsulated and therefore non-typeable. Most severe infections are caused by H. influenzae strains belonging to the capsular serotype b. In this slide agglutination test, agglutination occurs when a suspension of the isolate reacts with serotype-specific antisera.

This test is approved for New York patient testing.

Haemophilus influenzae, Type B, Antigen Detection, LA print

Specific soluble bacterial capsular polysaccharide antigens accumulate in CSF, serum, or urine. This is a presumptive latex agglutination test for the direct qualitative detection of bacterial antigen. Visible agglutination occurs when a sample containing a bacterial antigen reacts with specific polyclonal antibody-coated latex particles. This test is not intended as a substitute for a properly performed Gram stain and bacterial culture. Confirmatory diagnosis of bacterial meningitis is only possible with appropriate culture procedures. Samples with extremely low levels of antigen may yield negative results. Nonspecific reactions are known to occur, especially with urine samples. Cross-reactions and interference by rheumatoid factor and other substances have also been reported.

This test is approved for New York patient testing.

Hantavirus Antibodies (IgG, IgM) with Reflex to Confirmation print

Two major groups of hantaviruses are recognized based on clinical presentation. The first group includes Sin Nombre Virus, which causes hantavirus pulmonary syndrome, a severe and possibly fatal form of acute respiratory distress. A second group of hantaviruses (including Seoul, Hantaan, Dobrava, and Puumala viruses) causes hemorrhagic fever with renal syndrome, a condition not typically seen in the United States. Sera are initially screened for IgG and IgM antibodies recognizing the nucleocapsid protein common to all hantaviruses.
All screen IgM positive samples are then tested for SNV-specific IgM at an additional charge; further, any screen IgM positive samples that are also screen IgG positive are tested for SNV-specific IgG at an additional charge.
A positive result in the screening ELISA but a negative result in confirmatory assays may indicate reactivity to a hantavirus causing hemorrhagic fever with renal syndrome.

If result code Hantavirus IgG is >=2.00 and Hantavirus IgM is >=2.00 then Sin Nombre Virus IgG Confirmation, IBL is performed at an additional charge (CPT 86790).
If Hantavirus IgM is >=2.00 Sin Nombre Virus IgM Confirmation, ELISA will be performed at an additional charge (CPT 86790)

Herpes Simplex Virus (HSV), Conventional Culture print

Classically, HSV-1 infections are acquired in early childhood and are often asymptomatic or subclinical, but may produce oral lesions while HSV-2 is often acquired post-adolescence and manifests as genital infections with lesions. Current adult sexual behavior has allowed for oral HSV-2 infections and genital HSV-1 infections that are indistinguishable from the classic infections without identification of the virus. This assay uses cell culture methods that allow for HSV-1 and HSV-2 growth and isolation followed by a specific antiserum immunofluoresence assay for virus identification.

This test is approved for New York patient testing.

Herpes Simplex Virus 1 (IgG), Type-Specific Antibody (HerpeSelect®) - NEW! print

Herpes Simplex Virus (HSV) is responsible for several clinically significant human viral diseases with severity ranging from inapparent to fatal. Clinical manifestations include genital tract infections, neonatal herpes, meningo-encephalitis, keratoconjunctivitis, and gingivostomatitis. There are two HSV serotypes that are closely related antigenically. HSV Type 2 is more commonly associated with genital tract and neonatal infections, while HSV Type 1 is more commonly associated with infections of non-genital sites. Specific typing is not usually required for diagnosis or treatment. The mean time to seroconversion using the type specific assay is 25 days. The performance of this assay has not been established for use in a pediatric population, for neonatal screening, or for testing of immunocompromised patients.

Detection of HSV type-specific IgG in CSF may indicate central nervous system (CNS) infection by that HSV type. However, interpretation of results may be complicated by a number of factors, including low antibody levels found in CSF, passive transfer of antibody across the blood-brain barrier, and serum contamination of CSF during CSF collection. PCR detection of type-specific HSV DNA in CSF is the preferred method for identifying HSV CNS infections

The HerpeSelect® test system utilizes recombinant type-specific HSV-1 and HSV-2 antigens to detect type-specific IgG antibodies. Detection of IgG to both HSV-1 and HSV-2 in a single specimen therefore indicates dual infection by HSV-1 and HSV-2. In-house validation studies revealed a sensitivity of 100% for both the HSV 1 IgG ELISA and the HSV-2 IgG ELISA when compared to Western blot; specificity was 98% for both assays.

Due to the ubiquitous nature of HHV-7 infection, >80% of individuals in the general population exhibit HHV-7 IgG titers >=1:20; however, only 5% of these individuals exhibit titers >1:80. Thus, HHV-7 IgG titers >=1:160 are suggestive of recent HHV-7 infection. Detection of HHV-7 specific IgM is also indicative of recent infection.

Histone antibodies can be used to verify the diagnosis of drug-induced lupus caused by drugs such as procainamide and hydralazine. Histone antibodies are present in drug-induced lupus (96%), idiopathic SLE (50%), and occasionally, other collagen vascular diseases. Histone antibody in drug-induced lupus is the only specific anti-nuclear antibody detected; therefore the lack of histone antibody or the presence of other specific anti-nuclear antibodies makes the diagnosis of drug-induced lupus unlikely.

Conventional laboratory identification methods used to identify Histoplasma capsulatum include growth on fungal media, growth rate, and colonial and microscopic morphology. Once the organism begins to grow in culture, it may take many days or weeks of additional growth before the characteristic microscopic appearance of sportulation is observed. This test utilizes a chemiluminescent-labeled, single-stranded DNA probe that hybridizes to specific ribosomal RNA sequences that are unique to H. capsulatum. Colonies are identified as soon as growth is visible, with no need to wait for sportulation to occur. The sensitivity and specificity of this test both approach 100%.

This test is approved for New York patient testing.

The measurement of HIV p24 (core) antigen is performed by the Immune Complex Dissociation (ICD) modification of the standard p24 antigen assay. This modification results in a significant increase in the sensitivity of the p24 antigen assay. All specimens found positive are confirmed by neutralization for an additional charge. Quantitation of p24 antigen has been shown to be useful for detection of circulating, replicating, as well as nonviable HIV. The measurement of p24 antigenemia using the ICD modification may be of significant value for the detection of early infection and as a marker of disease progression and therapeutic response. Furthermore the p24/ICD assay has shown significant value for the early detection of HIV infection in neonates and may supplement other diagnostic tests for neonatal infections, such as HIV-1 PCR. Reactive specimens are confirmed by a neutralization method for an additional charge.

HIV-2, a retrovirus related to HIV-1, can cause immunosuppression and AIDS. The CDC (MMWR 41:rr12, 1992) recommends only specimens repeatedly reactive on combination HIV-1/2 EIA assay, negative or indeterminate on HIV-1 Western blot, and positive on HIV-2 EIA be tested by HIV-2 Immunoblot. An exception to this recommendation is a positive result by HIV-1 blot in a patient with risk factors for HIV-2 infection. Due to the strong serologic crossreaction between HIV-1 and HIV-2, it is essential that all specimens sent for HIV-2 Immunoblot also have HIV-1 Western blot results available (including the bands detected) in order to meaningfully interpret the HIV-2 Immunoblot results.

Hypersensitivity Evaluation II - NEW! print

Hypersensitivity Pneumonitis (an inflammatory lung disease) may be demonstrated by detection of precipitating antibodies to a variety of inhaled antigens from organic dusts or molds. A positive test does not always indicate active disease and should be supported by historical and clinical evidence, since some asymptomatic individuals may develop precipitins to one or more antigen types. A negative test does not preclude a diagnosis of hypersensitivity and should be evaluated along with other clinical findings.
