A CBAC worker gave her the good news her result was negative.
"They couldn't understand why I'd been missed off the list, and that they'd had my result back after about three days, but for some reason it wasn't passed on."
Fortunately, as she and her partner continued self-isolating at home, her symptoms cleared up a few days after her test.
"I wasn't worried about my own health, but what if there were people out there who had symptoms and were still waiting?" Schikker said.
"And I didn't want to be that person who went to the supermarket and then they call you and say 'actually you've got it'."
Wellsouth medical director and GP Dr Stephen Graham said he had not heard of any similar delays.
For tests carried out at a CBAC, the assessment centre informed patients of negative results.
Those with positive results were notified by Public Health South, a division of the Southern District Health Board that was carrying out contact tracing.
Although all results from a CBAC were also sent to a patient's nominated GP, WellSouth did not expect GPs to routinely notify such patients.
When the test was carried out by a GP, they were responsible for informing the patient of the result.
