DNA Testing in Iowa: Legal Collection & At-Home Kits

You can test at GameDay DNA collection sites or use an at‑home cheek‑swab kit for private peace of mind. Iowa Child Support explains in its resource on Paternity & Genetic Testing that it can only perform genetic testing when paternity has not yet been legally established and that testing is available in both court and administrative paternity actions; its page on Administrative Paternity Establishment adds that the administrative process is used when a child is under 19 and Iowa has jurisdiction over the alleged father.

Iowa law requires courts to order genetic testing when a party in a paternity case requests it. The blood‑ and genetic‑test statute Iowa Code § 600B.41 states that in a proceeding to establish paternity, the court may on its own motion, and upon request of a party shall, require the child, mother, and alleged father to submit to blood or genetic tests, and that if testing shows at least a 95% probability of paternity there is a rebuttable presumption the alleged father is the father; Iowa Legal Aid’s Paternity Questions and Answers explains that if you tell the Child Support Recovery Unit (CSRU) you do not believe you are the father, CSRU will obtain an order requiring you to submit to genetic testing and will pay for the testing initially.

Most legal paternity tests in Iowa use buccal‑swab (cheek‑swab) DNA samples from the child and the alleged father, and often from the mother. Iowa Legal Aid notes in its paternity Q&A that genetic testing is commonly used in child‑support cases and that a likelihood greater than 95% creates an assumption that the man is the father, while Iowa court‑ordered‑test explainers such as Court Ordered Paternity Test in Iowa state that when the court or CSRU orders a test, all parties submit DNA samples via a simple cheek swab and the results are then reviewed by the court to determine paternity.

For at‑home kits, use the sterile swabs in your kit, rub firmly along the inside of each cheek for the full time listed in the instructions, let the swabs air‑dry, and seal them in labeled envelopes before mailing. While home kits use the same basic cheek‑swab technique as legal tests, Iowa’s Paternity & Genetic Testing resource makes clear that CSRU genetic testing is done under an official administrative or court order and that only those supervised, chain‑of‑custody tests—not private at‑home kits—are used to legally establish paternity or overcome an existing paternity determination under sections 600B.41 and 600B.41A.

GameDay DNA provides results by secure online portal or encrypted email, with printed reports available for legal tests. In state‑handled cases, CSRU’s Administrative Order for Genetic Testing form explains that CSRU issues an order requiring the alleged father, mother, and child to appear for testing and warns that if the alleged father does not appear, CSRU will enter a default administrative order finding him to be the father; Iowa Legal Aid’s paternity Q&A notes that after testing, if it is impossible for the man to be the father CSRU will stop trying to establish support, but if the likelihood is greater than 95% he is assumed to be the father, and Arenson Law’s overview of court‑ordered tests adds that in court cases parties receive results through the court or CSRU and a paternity order is entered when biological fatherhood is confirmed.

Yes—Iowa statutes provide that properly conducted genetic‑test results are admissible and can create a presumption of paternity. Under Iowa Code § 600B.41, certified test results are admissible without third‑party foundation testimony, and when an expert concludes that the alleged father is not excluded and the probability is 95% or higher, there is a rebuttable presumption that he is the father; the code also specifies deadlines and procedures for challenging the results, and Iowa Legal Aid emphasizes that if you do not timely challenge tests showing more than a 95% likelihood, you will be treated as the father for support purposes unless you later overcome paternity using additional testing under § 600B.41A.

Either parent, the child (through a representative), or the state (through the Child Support Recovery Unit) may be involved in establishing paternity. Iowa Legal Aid’s paternity Q&A explains that paternity can be established by both parents signing a paternity affidavit at the hospital or by CSRU or a parent filing a court action to determine paternity, while CSRU’s materials on Administrative Paternity Establishment describe how Iowa Child Support uses the administrative process to establish paternity when a child is under 19 and Iowa has jurisdiction over the alleged father, and then, if needed, requests genetic testing and enters administrative orders.

In special situations—such as when an alleged father is already a legal parent, is deceased, or cannot be tested—Iowa law allows genetic evidence to overcome or support existing paternity determinations. Section 600B.41A permits actions to overcome previously established paternity if subsequent blood or genetic testing indicates that the previously established father is not the biological father, and legal summaries of Iowa paternity law note that blood or genetic testing conducted under § 600B.41 or chapter 252F must be used in actions to overcome paternity; courts may also consider testing of other alleged fathers and weigh genetic results with other evidence when deciding whether to maintain or disestablish paternity in complex cases.
