  • Tissue Transglutaminase (tTG) IgA

    Tissue Transglutaminase (tTG) IgA Ordering Recommendation Recommended single screening test for IgA-competent individuals with suspected celiac disease. (IgA testing recommended to identify IgA competence.). May aid in monitoring adherence to gluten-free diet in celiac disease-confirmed patients. Mnemonic Methodology Semi-Quantitative Enzyme-Linked Immunosorbent Assay Performed Mon-Sat Reported Within 24 Hours New York DOH Approval Status This test is New York DOH approved. Specimen Required Patient Preparation: Collect: Serum separator tube (SST). Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum to a Standard Transport Tube. (Min: 0.3 mL) Storage/Transport Temperature: Frozen. Unacceptable Conditions: Refrigerated. Remarks: Stability: After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid freeze/thaw cycles) Reference Interval 3 U/mL or less 4-10 U/mL Negative Weak Positive 11 U/mL or greater Positive Interpretive Data Presence of the tissue transglutaminase (tTG) IgA antibody is associated with glutensensitive enteropathies such as celiac disease and dermatitis herpetiformis. tTG IgA antibody concentrations greater than 40 U/mL usually correlate with results of duodenal biopsies consistent with a diagnosis of celiac disease. For antibody concentrations greater or equal to 4 U/mL but less than or equal to 40 U/mL, additional testing for endomysial (EMA) IgA concentrations may improve the positive predictive value for disease. Note Testing for tTG IgA antibodies is recommended as an initial screen to identify patients at risk for celiac disease, and in whom duodenal biopsy should be performed to confirm disease. Some patients may have positive tTG IgA but negative EMA IgA and/or deamidated gliadin peptide (DGP) IgA results, which may be associated with false positivity or may indicate early disease. Close clinical correlation with continued testing may be indicated in patients with a family history of or who are at increased risk for celiac disease. A positive serology but normal biopsy may also indicate a gluten-free diet (GFD) prior to testing, latent disease, or early enteropathy. Re-challenge with a gluten diet may be recommended if GFD had been initiated prior to subsequent testing. In the case of latent or early disease, HLA DQ2 and DQ8 testing may be necessary to determine risk for disease. For patients with a high degree of suspicion for celiac disease and who test negative for tTG, EMA and/or DGP IgA tests, selective IgA deficiency should be considered and testing for tTG, EMA and/or DGP IgG antibodies performed. If serology is negative and suspicion for celiac disease is strong, intestinal biopsy may be warranted. Biopsy is particularly important for patients with diarrhea, steatorrhea, weight loss, failure to thrive, or with inherited genetic deficiencies such Down or Turner syndrome.

  • Tissue Transglutaminase (tTG) IgG

    Tissue Transglutaminase (tTG) IgG Ordering Recommendation Recommended single screening test for IgA-deficient individuals with suspected celiac disease.

Mnemonic Methodology Semi-Quantitative Enzyme-Linked Immunosorbent Assay Performed Mon-Sat Reported 1-2 Days New York DOH Approval Status This test is New York DOH approved. Specimen Required Patient Preparation: Collect: Serum separator tube (SST). Specimen Preparation: Remove serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to a Standard Transport Tube. (Min: 0.5 mL) Storage/Transport Temperature: Refrigerated Unacceptable Conditions: Refrigerated. Remarks: Plasma. Hemolyzed or severely lipemic specimens. Stability: After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year Reference Interval 5 U/mL or less 6-9 U/mL Negative Weak Positive 10 U/mL or greater Positive Interpretive Data The tTG IgG assay may aid in the diagnosis of gluten-sensitivity enteropathy (i.e., celiac disease, dermatitis herpetiformis) in tTG IgA negative patients with confirmed IgA deficiency. A negative tTG IgG test alone does not rule out gluten-sensitive enteropathy.

  • Tryptase

    SARS-CoV-2 (COVID-19) Ordering Recommendation Use to detect the novel coronavirus (SARS-CoV-2). Mnemonic Methodology Qualitative Nucleic Acid Amplification (NAA) Performed Mon-Sat Reported 1-2 days New York DOH Approval Status This test is New York DOH approved. Specimen Required Patient Preparation: Collect: Nasopharyngeal swab, oropharyngeal swab, nasal swab, or saliva. To ensure the highest quality results, a nasopharyngeal swab is recommended. Specimen Preparation: Nasopharyngeal swab: Place in viral transport media Liquid Amies, or saline (minimum volume 1.2mL). Place each specimen in an individually sealed bag. Oropharyngeal or nasal swab: Place in viral transport media Liquid Amies, or saline (minimum volume 1.2mL). Swab Collection Kit. Place each specimen in an individually sealed bag. Saliva: Transport in COVID-19 Saliva Collection Tube Storage/Transport Temperature: Frozen. Unacceptable Conditions: Undiluted saliva. Saliva submitted in anything other than a Saliva Collection Tube. Swabs not in media. Wood swabs, calcium alginate swabs. Media with guanidine-containing materials, 'molecular media' that indicates inactivation of pathogens and preservation of RNA/DNA, charcoal media. Specimens sent in tubes with pop-top lids/caps. Specimens in glass tubes. Remarks: Stability: Swabs: Ambient: Unacceptable; Refrigerated: 2 days; Frozen: 1 month Saliva: Ambient: 5 days; Refrigerated: 5 days, Frozen: 5 days Reference Interval Interpretive Data This test should be ordered for the detection of the 2019 novel coronavirus SARS-CoV-2 in individuals who meet SARS-CoV-2 clinical and/or epidemiological criteria. The Coronavirus SARS-CoV-2 (COVID-19) by nucleic acid amplification test is for in vitro diagnostic use under the FDA Emergency Use Authorization (EUA) for U.S. laboratories certified under CLIA to perform high complexity tests. Not Detected results do not rule out the presence of PCR inhibitors in the patient specimen or assay-specific nucleic acid in concentrations below the level of detection by the assay. Detected results are indicative of the presence of SARS-CoV-2 RNA. Due to the complexity of nucleic acid amplification methodologies, there may be a risk of false-positive results. Clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status. Reliable results are dependent on adequate specimen collection, transport, storage, and handling.

  • Glomerular Basement Membrane Antibody

    Glomerular Basement Membrane Antibody, IgG (IFA) Ordering Recommendation May be useful in detecting glomerular basement membrane (GBM) antibodies. Combined use of IFA Glomerular Basement Membrane Antibody, IgG by Multiplex Bead Assay and IFA (2008403 ) may improve diagnostic sensitivity for disease. If positive, may be useful for monitoring treatment response. Mnemonic GBM-G IFA Performed Mon-Sat Methodology Indirect Fluorescent Antibody Reported 1-3 Days New York DOH Approval Status This test is New York DOH approved. Specimen Required Patient Preparation: Collect: Serum separator tube. Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transport 1 mL serum. (Min: 0.5 mL) Storage/Transport Temperature: Refrigerated. Unacceptable Conditions: Remarks: Stability: After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles) Reference Interval Negative Interpretive Data When present, IgG antibody to glomerular basement membrane (GBM) antigen detected by either indirect fluorescent antibody (IFA) or multiplex bead assay helps support a diagnosis of Goodpasture syndrome. However, the combined result of both assays performed during initial evaluation improves the diagnostic sensitivity for disease. A positive result in one or both assays should be confirmed by renal biopsy. This test was developed and its performance characteristics were determined by CDL. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
