Testing Frequently Asked Questions
Specimen Requirements Expand All
What kind of specimens do you accept?
PreventionGenetics accepts whole blood, purified DNA, cell cultures, and a number of other specimen types. Details are listed on our Specimen Requirements & Shipping page.
Is a separate tube of blood required for each test?
No, only one tube of the required 3 ml - 5 ml of blood will be sufficient to perform multiple tests. Blood should be collected in an EDTA (purple top) or ACD (yellow top) tube.
I am drawing a specimen from an infant. What is the minimum amount of blood required?
We require a minimum of 1 ml of whole blood in an EDTA (purple top) or ACD (yellow top) tube.
What is the stability of a blood specimen?
See our Specimen Requirements & Shipping page for more information. At room temperature or refrigerated, a blood specimen is stable for up to 8 days. Fresh blood specimens are preferred. If frozen, a blood specimen is stable for up to 1 month before shipping.
Does PreventionGenetics accept DNA extracted in other laboratories?
Yes, PreventionGenetics accepts purified DNA. We request that DNA be sent in a screw cap tube with at least 5µg – 10µg of purified DNA at a concentration of at least 20 ng/µl for NGS and Sanger tests and at least 5µg of purified DNA at a concentration of at least 100 ng/µl for gene centric aCGH, MLPA, and CMA tests, minimum 2 µg for limited specimens. For requests requiring more than one test, send an additional 5 µg DNA per test ordered when possible. We require that concentration, composition of the solute and identity of the specimen be clearly indicated on the DNA tube and/or Test Requisition Form. PreventionGenetics does not accept products of whole genome amplification or other amplification products.
What are the requirements for a prenatal specimen?
We accept fetal DNA, fetal tissue, cultured fetal cells, or direct CVS/amniotic fluid. However, acceptable specimen type is dependent on the fetal testing requested. Culture and send at least two T25 flasks of confluent cells. Multiple test requests may also require additional flasks. Please contact us for details. Most tests can also be performed using 5 µg of purified DNA. Retention of a back-up cell culture is required for NextGen Sequencing (NGS) requests and strongly recommended for other prenatal testing requests. PreventionGenetics offers cell culturing. Cell culturing should be ordered separately if needed. Where possible, please ship prenatal specimens so that they will arrive at PreventionGenetics no later than Thursday in the work week. When ordering shipping labels for prenatal specimens or kits for prenatal parental specimens, please note "prenatal" in the comments field on the kit order page. A signed Health Care Provider's Statement, which can be found within our Prenatal Test Requisition Form & Provider Statement on our Forms page, is required for all prenatal tests with ongoing pregnancies. See our Prenatal Testing Guidelines for more information.
What paperwork do I need to include with each specimen?
A completed Test Requisition Form, found on our Forms page, must accompany each specimen. Incomplete paperwork will delay testing.
Shipping Expand All
How do I send a specimen?
See our Specimen Requirements & Shipping page for more information. Specimens should be shipped in a crushproof, insulated container. Label all specimen containers with the patient's name, date of birth, and/or ID number. At least two identifiers should be listed on specimen containers. Specimen deliveries are accepted Monday-Saturday for all specimen types. However, urgent and/or sensitive specimens, such as cell cultures, direct amniotic fluid, or direct chorionic villi, are preferred to arrive Monday-Thursday. Urgent/sensitive specimens shipped on Thursday should be marked for overnight delivery; those sent Friday should be marked for overnight and Saturday delivery. Contact us to make arrangements. All specimens should be accompanied by a completed Test Requisition Form, found on our Forms page.

Turnaround Times Expand All
How long do results take?
Please see our Turnaround Times page for details.
Do you have a STAT option for ordering a test?
Yes, we offer STAT or RAPID options for most tests on our menu, including PGxome, Custom Panels, NGS panels,Sanger sequencing and gene-centric aCGH. Please see each Test Description and our Turnaround Times page for details.
How long do prenatal tests take?
All tests related to ongoing pregnancies are performed with an expedited TAT. Targeted prenatal tests for known familial variants are completed within 8 days on average. NGS panels are completed within 14 days on average. For more information on prenatal TAT by test method, please refer to the Prenatal Guidelines.
What is your procedure to add on another test for a patient who was tested previously at PreventionGenetics?
Additional tests can be ordered by faxing the Add-On Test Requisition Form to 715-384-3661. We will contact you if we require a new specimen to complete the requested testing.
Do I have to send another specimen if I am adding on a test?
Usually not. PreventionGenetics retains unused DNA from previous tests. If a blood specimen was originally sent, we nearly always have sufficient DNA to perform additional tests. If a limited amount of purified DNA was originally sent, or if the specimen originated in NY state, then a second specimen will often be required.
Billing Expand All
What is your tax identification number?
PreventionGenetics LLC Tax Identification Number is 83 0343803.
Does Preventiongenetics accept insurance?
PreventionGenetics will file an insurance claim on behalf of a patient with any commercial insurance company.
What is necessary for PreventionGenetics to bill insurance?
Page 3 of the TRF indicates the information needed for insurance billing. This section must be completed in its entirety before testing can begin. This includes additional information such as pre-authorization information, pertinent medical record information, and/or a letter of medical necessity.
If insurance has been verified and preauthorization obtained, why would my patient receive an invoice for charges (partial or total)?
Preauthorization does not guarantee payment. Insurance companies determine payment and what charges will be billed to the patient after a medical claim is filed.
As a friendly reminder that the test has been completed and there is the possibility of some financial obligation from the patient, an invoice will be mailed to the patient after testing is complete. The invoice will indicate that an insurance claim has been filed, and no payment is due at this time. A monthly statement indicating an insurance claim is in process will also be mailed to the patient. No payment will be required from the patient until the insurance claim has been processed and closed. Once insurance payment has been received, the monthly statement will indicate the remaining balance and note that the remaining amount is now due from the patient.
The patient is responsible for notifying PreventionGenetics of the status of the explanation of benefits (EOB) and remitting any funds received directly from the insurance company to PreventionGenetics.
The patient is responsible for any portion of the test fee not covered by the insurance company for any reason including, but not limited to: co-payments, co-insurance, unmet deductibles, or non-covered services.
How can patients find out how much their insurance will cover?
While a benefit investigation does not guarantee payment, PreventionGenetics can assist with a benefit investigation of insurance coverage. For assistance please complete the insurance benefit investigation form found on our website or call our insurance specialists at 715-387-0484.
Where are the specific CPT codes and prices for the test I'm ordering?
A spreadsheet containing CPT codes and prices for our tests can be found here. Each test description also lists the CPT codes for testing.
Does PreventionGenetics participate in any Medicare or Medicaid plans?
We are a contracted provider for Medicare and Wisconsin Medicaid. At this time we do not accept any other state's Medicaid.
The patient must meet Medicare criteria for genetic testing in order for the services provided to be considered covered and reimbursable by Medicare. We do require Medicare patients to sign a completed advance beneficiary notice (ABN) in advance of testing to acknowledge financial responsibility should the testing not meet Medicare criteria for covered service.
Is PreventionGenetics contracted with private insurance companies?
Does PreventionGenetics bill institutions?
Yes, PreventionGenetics will invoice the institution or provider directly for the total test fee once the report has been sent to the ordering healthcare provider.
Does PreventionGenetics offer patient self-pay?
Yes, we will bill the patient directly. The individual accepting financial responsibility for the test fees must sign the acknowledgement statement on the Test Requisition Form. The responsible billing party must be at least 18 years old.
Does PreventionGenetics require pre payment for self-pay testing?
No. We do not bill for the test until testing is complete. We do not require a credit card to be on file; however, having a credit card authorization on file allows for easy payment processing once the test has been completed. PreventionGenetics accepts Visa, MasterCard, and Discover. We can also accept payments by bank wire transfer, Automatic Clearing House (ACH), or check.
Does PreventionGenetics offer different pricelists for different payment types?
Regardless of the nature of payment or payer, we strive to provide the lowest prices in the market; therefore, our prices do not vary for different payment options. Our prices are transparent and openly published on our website. We offer three (3) convenient payment options for testing services: we can bill the ordering institution/provider directly (institutional billing), we can bill the patient directly (self-pay), or we can bill the patient's commercial insurance company (insurance billing).
What date of service does PreventionGenetics use?
Date of service (DOS) on the invoice will be the accession date. If the DOS must reflect the date that testing is started (rather than accession date) please contact our billing team to make arrangements.
What are the payment terms?
Payment is due 30 days from the date of the invoice or 30 days from the date the insurance claim closes. Please contact our billing team to discuss payment plans if necessary.
What happens if we cancel a test?
If you need to cancel a test, please contact our client services department.
Test Information Expand All
Does PreventionGenetics provide detailed information for each test?
Yes, a detailed Test Description for each test is freely and easily available from our web site. Just search a test to begin.
Can we order testing for a specific mutation, or do we have to order the entire gene?
We offer single (Test #100, $250), double (Test #200, $370) or triple (Test #300, $440) variant testing for any of the genes on our test menu. These tests are typically performed for relatives of the probands or for confirmation of test results from other labs. Most genes are fully developed in our laboratory and ready to order. There are, however, some genes that may require an additional 2-3 weeks for development. Search for your gene of interest on our Targeted Variants landing page for details.
Please specify the mutation fully in the comments section at the bottom of page 1 of the Targeted Variant Test Requisition Form.
Do you offer Deletion/Duplication testing?
Yes, our exome based tests are validated to detect copy number variants. Genes and panels ordered using exome based sequencing panels now includes analysis of copy number variants.
PreventionGenetics offers a custom designed, high probe density, gene-centric aCGH test (our Test #600), which targets many of the genes on our test menu. Please specify the desired genes in the comments section at the bottom of page 1 of the Test Requisition Form.
Do you offer free family targeted variant testing?
PreventionGenetics offers no-cost targeted testing for pathogenic, likely pathogenic, and uncertain variants in family members of patients (also known as probands) tested at our laboratory. See our Family Targeted Variant Testing Policy for more information. For probands whose results were issued prior to August 1, 2020, we will still allow for no-cost targeted testing in up to two family members for any Variants of Uncertain Significance (VUS) identified in the proband.
Do you require positive control specimens for targeted mutations?
If the family member was tested at an outside laboratory, we recommend that you submit a specimen from that individual to serve as a positive control. The positive control specimen will be tested free of charge, and no report will be provided. If a positive control is not provided, negative results will carry a limitation stating that PreventionGenetics did not have the opportunity to verify that we can detect the variant in this family. Positive controls are required for targeted prenatal testing.
How do I order a single gene or subset of genes from a NextGen, Sequencing panel?
Yes. Please indicate “interpret only XXXX gene” on the Test Requisition Form. The price will remain the list price. Free reflex testing to remaining genes on the panel is available if desired. Alternatively, a single gene can also be ordered on our Custom Panel.
Can I order a NextGen Sequencing panel update?
If our PG-Select NextGen Sequencing panel is updated to offer additional genes, we will offer a panel update for a charge of $640. Please contact us to confirm that we have adequate DNA remaining and complete our Add-On Test Requisition Form, found on our Forms page. Specifying NextGen Sequencing panel of interest and "Update". The interpretation will include only the genes that have not been previously analyzed. CPT codes for newly added genes apply.
Contact us with questions.
If I order a subset of genes on a panel, can I reflex to the rest of the panel?
Yes. If a single gene or any subset of genes is ordered on a panel, free reflex testing to remaining genes on the panel is available if desired. Reflex testing to PGxome from a Custom Panel is also available. See our Custom Panel Test Description for details.
