  • FAQs | CDL

    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). 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 2-5 days. We recommend contacting us ahead of time for more details based on the specific test being administered. 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] 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. How Long Does it Take to Receive COVID test results? The standard turnaround time for PCR-COVID test results is 24 hours. 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. 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. 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. 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. 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. 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. The email will be from labreport@clinicaldiagnosticlab.com*. Your date of birth in the format ‘YYYYMMDD’ is your password to be used to open this report. *Note: Always check your spam/junk mail if you have not received your results in your standard inbox! **The easiest method of finding your results is to type the email address “labreport@clinicaldiagnosticlab.com” in your email’s search bar as results are often difficult to find when sent to the spam/junk folder.

Even though increasing ranges are reflective of increasing concentrations of allergen-specific IgE, these concentrations may not correlate with the degree of clinical response or skin testing results when challenged with a specific allergen. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis.

Persistence is defined as moderate or high levels of IgG and/or IgM B2GPI antibodies detected in two or more specimens drawn at least 12 weeks apart (J Throm Haemost. 2006;4:295-306). B2GPI results greater than 20 SGU (IgG) and/or SMU (IgM) are considered positive based on the cutoff values established for this test. International reference materials and consensus units for anti-B2GPI antibodies have not been established (Clin Chim Acta. 2012;413(1-2):358-60; Arthritis Rheum. 2012;64(1):1-10.); results can be variable between different commercial immunoassays and cannot be compared. Strong clinical correlation is recommended for a diagnosis of APS. Low positive IgG and IgM B2GPI antibody levels should be interpreted in light of APS-specific clinical manifestations and/or other criteria phospholipid antibody tests.

  • Cardiolipin Antibody, IgM

    Cardiolipin Antibody, IgM Ordering Recommendation Acceptable initial test when antiphospholipid syndrome (APS) is highly suspected.

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.
