Frequently asked questions 01 Do I need to schedule an appointment if I purchase the test online? Yes — once you place your order, you'll be prompted to schedule an appointment at one of our laboratory locations. Walk-ins are not permitted for prepaid panels to ensure proper time is set aside for your visit. 02 Will I receive a kit in the mail? No — there is no kit mailed to your home. All testing is performed in our certified laboratory. After purchasing your panel, you'll simply come in for your scheduled blood draw. 03 Do I need to bring anything to my appointment? Just bring a valid photo ID and your email confirmation. There’s no insurance information needed — we’ve already got you in the system. 04 Do I need a doctor’s referral to order a test? Not at all. Our panels are available without a referral, prescription, or insurance. That’s part of what makes this process simple and accessible. 05 How will I receive my results? Results are delivered securely via email in PDF format within 2–5 business days. You’ll be notified as soon as they’re ready. 06 Can I use my HSA or FSA card? Yes — many patients successfully use HSA/FSA cards at checkout. Be sure to check with your plan provider for eligibility. 07 Can I get reimbursed by my insurance? Yes — depending on your insurance policy, you may be eligible for reimbursement by submitting your receipt directly to your provider. However, reimbursement is not guaranteed. Some insurance plans do not cover specific tests or may require additional documentation before testing. We strongly recommend contacting your insurance provider in advance to understand your options, if you wish to be reimbursed. 08 Is there a cancellation fee? Yes — if you cancel your order after purchasing online, a small cancellation fee of 3.4% will be applied to cover non-refundable transaction processing costs. 09 Are you Available for Walk-Ins or Do I Need to Schedule an Appointment? You are not required to schedule an appointment at our facility. We are available for walk-ins during the weekdays during our standard operating hours. However, we do recommend patients schedule appointments ahead of time, contact us via our email form, or call in advance to verify the availability of a Phlebotomist (if bloodwork is required). 10 How Long Does it Take to Receive my Lab Results? The turnaround time of a test varies depending on the test(s) being administered. Typically, a test will take around 24-72 hours. We recommend contacting us ahead of time for more details based on the specific test being administered. 11 I received my results but I'm having trouble opening them Results sent directly to your email will typically be password protected for your security. Passwords will be the Date of Birth of the patient in the following order: (Year/Month/Day). For example, if you're Date of Birth is January 31, 1980 your password will be the following: [ 1980/01/31 ] 12 How Will My Results be Delivered? If you provided a doctor's order/referral your results will be sent over directly to your referring physician. You can contact your physician directly for the results of your test (if they did not already contact you). If an order was not provided, you will receive your results via email. Your results will be delivered as a password protected PDF file. 13 How Long Does it Take to Receive COVID test results? The standard turnaround time for PCR-COVID test results is 24 hours. 14 What types of tests do you offer? We offer a wide variety of medical tests including, but not limited to, H.Pylori, Drug screenings, STD testing, COVID, FLU, standard blood panels, and far more. Please contact us for more information. 15 Are Children Permitted to Take a COVID test? Yes, children can take the PCR-Covid test. The cost of the test is the same for children. 16 Are there other options besides a Nasal Swab for the PCR-COVID test? The most effective method of testing for the COVID-19 Coronavirus is via a Nasopharyngeal swab. A cheek or throat swab can also be performed at the request of a physician; however, either of these methods can be inaccurate and may result in an inconclusive lab result. 17 What is the Difference Between a Rapid Test and a PCR test? The Rapid test (also known as the Antigen test) offers a fast turnaround time but is best used on patients showing symptoms. However, the rapid test results tend to be inaccurate when compared to the RT-PCR test. One can expect the results of a Rapid Test within 15 minutes. The RT-PCR (Polymerase Chain Reaction) test is considered the “Golden Standard” with regards to COVID tests. The PCR test is considered the more accurate version when testing for the COVID-19 virus. 18 Do I Need to Pick Up my Results in Person? While you may pick up results in person, the delivered lab results will be sent to your physician directly either through their portal or via fax. If an order was not provided, results will be sent to the email address provided when you schedule an appointment. 19 How do I Access my lab Results? If you came with a doctor’s order, Clinical Diagnostic Laboratories (CDL) will fax your lab results to your doctor’s office. We will also try to email results in a timely manner. However, if you do not receive your results after the given time frame, please follow up with CDL by emailing us at info@clinicaldiagnosticlab.com or call us at 703-430-1111.

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.

Remarks: Stability: After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year Reference Interval <=12 MPL Negative 13-19 MPL Indeterminate 20-80 MPL Low to Moderately Positive 81 MPL or above High Positive Interpretive Data The persistent presence of IgG and/or IgM cardiolipin (CL) antibodies in moderate or high levels (greater than 40 GPL and/or greater than 40 MPL units) is a laboratory criterion for the diagnosis of antiphospholipid syndrome (APS). Persistence is defined as moderate or high levels of IgG and/or IgM CL antibodies detected in two or more specimens drawn at least 12 weeks apart (J Throm Haemost. 2006;4:295-306). Lower positive levels of IgG and/or IgM CL antibodies (above cutoff but less than 40 GPL and/or less than 40 MPL units) may occur in patients with the clinical symptoms of APS; therefore, the actual significance of these levels is undefined. Results should not be used alone for diagnosis and must be interpreted in light of APS-specific clinical manifestations and/or other criteria phospholipid antibody tests.
