The Minister for Health says there's been no attempt to conceal information about waiting times for hospital diagnostics.
He was responding to reports that tens of thousands of patients are on hidden waiting lists within the health service.
In a statement this afternoon, Leo Varadkar says he has no interest in making things look better or worse than they are and the HSE plans to publish updated information on diagnostics again in the future.
But he says its important the information is accurate and comparable across hospitals, as currently it's not.
