Ordering information regarding a Tissue Transglutaminase (tTG) IgA test for Clinical Diagnostic Laboratories. 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.

Ordering information regarding an HPV Self Collection Screen for Clinical Diagnostic Laboratories. HPV Self-Collection Screening (HPV-SCS) Ordering Recommendation The HPV Cervical Cancer Self-Collection Test is a highly sensitive screening tool that enables patients to collect their own vaginal sample using an FDA-approved device. After collection, the specimen is processed using advanced nucleic acid amplification methods (typically PCR-based) to qualitatively detect high-risk HPV DNA associated with cervical cancer. This self-collected approach offers comparable diagnostic accuracy to traditional clinician-collected samples while minimizing discomfort and barriers associated with pelvic examinations, making it an effective option for early detection and timely clinical follow-up. Mnemonic HPV Self-Collection Screening (HPV-SCS) Methodology The specimen is processed using nucleic acid amplification techniques (generally PCR-based methods) to qualitatively detect the presence of high-risk HPV DNA. Performed Mon-Sat Reported Within 3-5 days Specimen Required Patient Preparation: Collect: Wash your hands and remove the sterile self-collection device before gently inserting it into the vagina up to the indicated marker. Rotate the device 2–3 times as instructed to collect an adequate sample, then carefully withdraw it. Refrain from douching, using intravaginal medications, or applying topical agents for at least 48 hours prior to collection. • Avoid sexual intercourse for 24–48 hours before sample collection. • If menstruating, confirm with the provider whether sample collection should be postponed until menses have ceased. Specimen Preparation: Immediately place the collection device into the provided vial containing the appropriate viral transport medium. Secure the vial cap tightly and gently invert the vial to mix the specimen with the medium. Ensure that the specimen is labeled accurately with patient identification and collection date/time. Storage/Transport Temperature: Maintain at 2–8°C during storage and transport. Avoid freezing unless the test kit instructions specifically allow it. Prompt transport to the laboratory is advised to maintain sample integrity. Unacceptable Conditions: Specimens that are unlabeled or improperly labeled. Inadequate sample volume or insufficient cellular material. Contaminated samples (e.g., with menstrual blood or external substances) beyond acceptable limits. Specimens showing leakage or compromised container integrity. Samples exposed to temperatures outside the recommended range prior to processing Remarks: Specimen source required. Stability: Reference Interval Negative Interpretive Data A positive result should be correlated with clinical history and may necessitate additional diagnostic procedures. Careful patient education on follow-up steps and interpretation of results is essential. This test should be used as a screening tool only; abnormal findings must be evaluated in conjunction with other clinical assessments.
