VIDEO: Delays in receiving Zika test results reported

WASHINGTON – The Centers for Disease Control and Prevention is recommending blood or urine testing for all pregnant women with possible Zika exposure through travel or because they live in an endemic area, regardless of whether they are symptomatic, Dr. Denise J. Jamieson said at the annual meeting of the American College of Obstetricians and Gynecologists.

Couples interested in conceiving who live in or have traveled to areas of active transmission should be alert for any signs of infection, no matter how slight; if they notice any, they should be tested for exposure before attempting conception, Dr. Jamieson, a medical officer with the CDC’s division of reproductive medicine, said in a video interview.

Unfortunately, she said at an update on the Zika situation, labs that process Zika blood and urine samples are backed up, and test results are being “unacceptably delayed.”

During a discussion period, some physicians in the audience complained of waiting up to 6 weeks for results. One said a local health department official told him that the CDC had a backlog of “a million tests.”

“We do not have a 1-million test backup,” Dr. Jamieson said. “But in some places there are still unacceptably long delays. This is not a test you can just check off on a form and send to a lab.”

Many of the tests are being funneled to the CDC’s Division of Vector-Borne Diseases in Ft. Collins, Colo.; that facility is experiencing a long turnaround time. Other samples are being handled in private labs with CDC contracts, but Dr. Jamieson said there’s an urgent need to expand the testing to many more commercial labs. There is no concrete plan for how or when this expansion will happen, however, she added.

Dr. Jamieson also discussed the CDC’s recommendation for managing pregnant women who have a positive serology or urine. These women should have serial ultrasounds every 3-4 weeks to track fetal brain development. Amniocentesis can positively confirm fetal exposure. A maternal-fetal medicine specialist should be on board if the fetus tests positive or if any concerning signs appear on imaging. Newborns can also be tested for exposure, as can placental and cord tissue.

On May 16, the World Health Organization released a comprehensive document describing a management algorithm for pregnant women who live in or travel to Zika-endemic areas.

Women who haven’t experienced signs and symptoms of an infection can proceed with routine care, and, if possible, an ultrasound before 18 weeks’ gestation and another at 28-30 weeks.

Women who have had signs of an infection should be tested for exposure. If negative, routine care with an early ultrasound and one at 28-30 weeks is indicated. If the results are positive, or if an early scan is concerning, patients should have a diagnostic ultrasound and amniocentesis, with referral to specialty care.

In the case of confirmed maternal exposure but normal early ultrasound, serial scans are indicated every month until delivery.

As a federal employee, Dr. Jamieson has no financial disclosures.
