Ordering information regarding a Hemoglobin A1C test for Clinical Diagnostic Laboratories. Hemoglobin A1C Ordering Recommendation The Hemoglobin A1c test is a vital tool for diagnosing and monitoring diabetes mellitus, as well as assessing prediabetes. Diagnostic levels are marked by values greater than or equal to 6.5%, while monitoring involves tracking long-term glycemic control in diabetes patients. Additionally, values between 5.7% and 6.4% signal an increased risk of developing diabetes. For patients with hemoglobin variants lacking hemoglobin A, the Fructosamine test is preferred for monitoring long-term glycemic control. Mnemonic Methodology Quantitative Capillary Electrophoresis Performed Mon-Sat Reported Within 1-2 days New York DOH Approval Status This test is New York DOH approved. Specimen Required Patient Preparation: Collect: Lavender (EDTA) Specimen Preparation: Transport whole blood in original tube. (Min: 1 mL) Storage/Transport Temperature: Refrigerated. Unacceptable Conditions: Tissue or urine. Samples frozen after 8 hrs of collection and samples frozen at temperatures less than -70C. Remarks: Stability: Ambient: 72 hours; Refrigerated: 1 week; Frozen: 3 months (Must be frozen within 8 hrs of collection at -70 to -80C) Reference Interval Components Available Separately Reference Interval No Hemoglobin A1C Less than 5.7 percent No Estimated Average Glucose By report Interpretive Data HbA1c values of 5.7-6.4 percent indicate an increased risk for developing diabetes mellitus. HbA1c values greater than or equal to 6.5 percent are diagnostic of diabetes mellitus. For diagnosis of diabetes in individuals without unequivocal hyperglycemia, results should be confirmed by repeat testing. Note This assay accurately measures hemoglobin A1c even in the presence of hemoglobin variants, provided hemoglobin A is present. For patients with known hemoglobin variants who lack hemoglobin A, it is recommended to monitor long-term glycemic control using the Fructosamine test CPT Code 83036 Components Component Test Code 0070427 0070428 Component Chart Name Estimated Average Glucose LOINC Hemoglobin A1C 27353-2 4548-4 Aliases Hemoglobin A1C A1C A1C Hemoglobin Glycated Hemoglobin Glyco HGB Glyco-Hb Glycosylated Hemoglobin HA1C HbA1c Hemoglobin A1C Hemoglobin A1C, Blood

Learn why our practice no longer accepts PPO insurance or Anthem HealthKeepers, what this change means for your care, and how we continue to prioritize accessible, patient‑focused treatment. Dear Valued Patient, We understand that navigating lab testing and insurance coverage can be confusing, stressful, and sometimes frustrating. Many patients expect that medically necessary lab tests will be fully covered by their insurance, only to be surprised by bills or claim denials. We want to take a moment to explain why this happens, and what options are available to you. Why Insurance Coverage Can Be Complicated Insurance companies often control which laboratories they will reimburse, and many have exclusive agreements with specific “preferred” labs. Even if your doctor orders a test that is medically necessary and has a preferred laboratory they wish to send it to, insurance may refuse to pay if the lab performing it is not on the insurer’s approved list. In addition: Claims can be denied for administrative reasons, not because the test lacks medical necessity. In 2023, studies showed that nearly 1 in 5 claims across commercial plans were denied, with out-of-network labs denied more than one-third of the time. Negotiated rates may not reflect the true cost of testing, leaving smaller or independent labs out-of-network and limiting patient choice. Large insurers sometimes rely on high-volume national labs (like LabCorp or Quest), which must process thousands of samples and often face delays, lost specimens, or reporting outside the necessary timeframe . “Insurance networks and claim rules can make testing feel more like a barrier than a service. That’s why we focus on transparency and patient choice.” Your Options: Affordable, Transparent Self-Pay To make testing accessible and predictable, we offer affordable self-pay pricing. Because all of our testing is performed in-house, locally, we can provide: Lower prices than national lab chains Faster turnaround times Greater accuracy and reliability If you choose to pay out-of-pocket, we will provide a superbill containing everything your insurance company needs to process a claim. This includes: CPT codes for all tests performed Diagnosis codes Our provider identifiers (NPIs) Itemized charges and documentation We are happy to assist you with any additional paperwork or information your insurer may request. Even if the claim is initially denied, we can provide supporting documentation to help you appeal. “We want you to have control over your care — and the ability to submit claims to your insurance if you wish.” Why Our Lab is Different Unlike large national laboratories: Everything is processed locally, in-house, giving us control over quality and timing We avoid unnecessary shipping, which reduces risk of lost or misreported samples Our focus is on patient-centered service, not volume This means you get your results faster, accurately, and at a fraction of the cost. We Are Here to Help We understand this situation is not your fault, and it’s not your choice. Insurance networks, coverage rules, and reimbursement policies are complex — even for providers. Our commitment is simple: Provide high-quality testing you can trust Offer transparent, affordable pricing Support you in navigating insurance reimbursement whenever possible “With self-pay options and superbill support, you can access the testing you need without unnecessary delays or surprises.” Take Action Today We make it simple to access testing services on your terms: If you have questions or need guidance about insurance or billing, please contact our team — we are happy to walk you through every step.

What the app can do is help you understand your lab numbers in a simple way and suggest potential solutions to achieve optimal lab results. It can show you trends, explain what certain markers usually relate to, and give you general wellness ideas. Think of it like a friendly guide that helps you make sense of your information — not a doctor and not a replacement for medical care. 15 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. 16 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. 17 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. 18 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. 19 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. 20 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. 21 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. 22 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. 23 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). 24 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. 25 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] 26 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. 27 How Long Does it Take to Receive COVID test results? The standard turnaround time for PCR-COVID test results is 24 hours. 28 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. 29 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. 30 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. 31 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. 32 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. 33 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.

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.
