We have attempted to address the most common questions we receive from patients and healthcare providers on our Frequently Asked Questions page. We look forward to working with you.
Kashi Toxicology's pharmacogenetics testing utilizes a simple buccal swab system to help your healthcare provider decide which medications and in what doses may work best based on your unique genetic profile.
What is the benefit of pharmacogenetic testing?While age, gender, and diet may affect a person's response to medication, genetics can also play a large role, particularly if you are taking more than one prescription drug. Pharmacogenetic testing can help healthcare providers understand how each patient's body processes medications, enabling them to determine which medications may be the best option, what may be the most effective doses, and how multiple medications may work together. With the results from genetic testing, your healthcare provider can personalize medication therapy, increasing your chance of successful treatment and a healthier life.
How do I know if I should be tested?Your healthcare provider will determine whether you will be tested based on your medical needs.
When are the results available?All Kashi Toxicology pharmacogenetic results are available in four to five business days from receipt of samples, appropriate payment information, and a completed test requisition. Overnight STAT testing is also available for an additional fee.
Are my results kept private?Kashi maintains your privacy in accordance with Health Insurance Portability and Accountability Act (HIPAA) regulations. Kashi does not store patient DNA and each specimen is securely discarded after completion of testing.
What is involved in the medication monitoring process?Your healthcare provider's staff will provide direction on how to submit a urine sample for testing. Please follow the instructions carefully. The collection device provided by your healthcare provider may contain instant-read test strips. Please do not tamper with the test strips. Your healthcare provider's staff will interpret the preliminary results, and may then send the sample to an outside laboratory, such as Kashi Toxicology, for further analysis and/or additional testing.
What happens once my specimen is sent to the lab?The lab will run a series of tests requested by your healthcare provider, which may include Urine Drug Testing, to confirm the levels of both prescribed and non-prescribed medication in your system. Your healthcare provider has selected Kashi Toxicology for testing of your specimen and may use these test results to personalize your treatment plan.
How do I pay for this test?The laboratory will bill your insurer directly. Then, your insurance company will send you an Explanation of Benefits (EOB). The EOB is not a bill. It is simply a statement that shows how your insurer processed the claim for the test. Depending on your insurance carrier, you may receive a statement for a co-payment or a deductible.
What is the difference between a screening test and a confirmatory test?Screening tests are performed using reagent based systems that determine the presence or absence of drug compounds in the urine. While these tests can identify groups or classes of drug compounds that may be present in a patient sample, they can rarely be used to identify a specific drug or drug metabolite. This is why they are known as non-specific assays, and are considered presumptive screening tests. Another test is needed to determine exactly what drug compound, and what quantity, has triggered the positive presumptive screen.
Confirmatory tests are the next step in the testing process. To further pin-point the identity of a drug, an alternate methodology that is specific and sensitive to each individual drug compound must be employed. Kashi utilizes a state-of-the-art technology known as Liquid Chromatography/Mass Spectrometry (LC/MS) to confirm the presence and amount of specific drug compounds at the molecular level. LC/MS is capable of detecting a wide variety of compounds, including drugs, and is considered the "gold standard" by experts in many fields.
Why are some tests confirmed and others not?Healthcare providers may select which test works best for their patient's unique needs. Some providers prefer confirmation on all presumptive positive screens, while others request confirmation of only select presumptive screens. Kashi strives to offer services tailored to every healthcare provider. If you have further questions, please contact our customer service representatives at (877) 879-1815.
How often will I be tested?Your healthcare provider will determine the frequency of your testing based on your medical needs.

My patient has a question about billing. May he/she contact Kashi Toxicology directly?Our billing department is always available to speak with patients about fees and insurance. Due to HIPAA regulations, patients will be asked to verify their identity prior to any protected health information being released.
What information does Kashi Toxicology need to bill my patient's insurance carrier?The information needed by healthcare providers to bill a patient will also be needed by Kashi. This includes addresses for insurance carriers, worker's compensation information, and pre-authorizations. Most providers' offices can print this information via a "face sheet" from their computer.
Why does the patient have to sign the requisition?The patient signature area(s) of the Kashi Requisition for Pharmacogenetic Urine Drug Testing provide more than just chain-of-custody documentation. A signature also documents the patient's awareness of their HIPAA rights, certifies that theirs is the sample provided, and allows Kashi to bill the patient's insurance, as well as supply results to the requesting party and ordering physician.
