Test kits at the centre of an SA Pathology bungle, which saw about 100 men receive false positive results for prostate cancer, are not to blame, supplier Siemens says.

SA Pathology executive director Ken Barr was earlier this week sacked and an independent review ordered after errors were uncovered when a urologist ordered new tests for about 30 patients who then returned negative results.

Siemens said an internal investigation and review showed its kits were not faulty, as was initially suggested.
