DNA tests backlog leave hundreds in genetic limbo

The National University of Science and Technology's (NUST) Innovation Hub is grappling with a backlog of more than 300 DNA tests, leaving hundreds of clients - including those involved in court cases and family disputes - facing prolonged uncertainty.

The backlog has been attributed to delays in the procurement of imported reagents required for DNA analysis, a challenge that has disrupted operations at one of Zimbabwe's key DNA testing facilities.

Established under the Government's drive to promote innovation, industrialisation and applied scientific research, the NUST Innovation Hub has grown into a critical provider of commercial DNA testing services, complementing its academic research mandate. The facility plays an important role in easing pressure on State forensic laboratories and private medical institutions, particularly in cases involving paternity disputes, criminal investigations and civil litigation.

DNA testing has increasingly become a cornerstone of court proceedings, providing objective scientific evidence. Demand has also surged due to migration-related documentation, inheritance disputes and family reunification cases.

However, the service has hit a major operational setback.

Several clients told this publication they have been waiting for results since October last year, while others who submitted samples in November say they have not been given clear timelines.

"I submitted my samples in early November and every time I call, I am told to wait. The delay is affecting my life and the court proceedings," said one client, who requested anonymity.

Another client said the prolonged waiting period has taken an emotional toll on their family.

"We have been waiting since October. The uncertainty is agonising for my family. We just need closure," the client said.

Confirming the backlog, NUST director of communication and marketing, Mr Thabani Mpofu, said the university is currently dealing with about 300 outstanding cases.

"We have a backlog of tests of about 300 cases, covering both forensic and paternity tests. These are cases that we are supposed to conduct and complete, and we are currently working to clear that backlog," he said.

Mr Mpofu attributed the delays to challenges in importing essential testing reagents.

"As you may be aware, these reagents are all imported. The importation process delayed the arrival of the reagents that we use for testing," he said.

He said the university has since received the reagents and has begun addressing the backlog.

"We have now received the reagents and we are clearing the backlog by the end of the month so that we can resume normal testing," said Mr Mpofu, adding that it would take between two and three weeks to process the accumulated cases.

Despite the delays, Mr Mpofu said the facility has continued to receive new samples, although clients are being informed in advance about the challenges.

NUST expects normal DNA testing services to fully resume by the end of January, once the backlog has been cleared.
