Test Iowa released a list of locationswhere the kits may be picked up. It's also possible to request that a kit be sent to a home. Rather than a nasal swab, the test kits require a saliva sample that Iowans will collect at home before shipping the sample to the State Hygenic Lab. The video below demonstrates the process and what stipulations are required for an accurate result. It's recommended that the sample be taken early in the morning because eating, drinking, smoking, or tooth brushing will contaminate the sample. This change in testing comes as cases continue to rise in Iowa, mostly among those not vaccinated against COVID-19. Disease Surveillance & Investigation Manager Josh Pikora says this is the case in Black Hawk County.
