Two men formerly employed by Randox Testing Services (RTS) have been arrested, and five interviewed under caution by Greater Manchester Police over the case.
The two arrested suspects are understood to have previously worked at another firm called Trimega Laboratories, which is also being investigated by police over potential manipulation that could affect child protection and family court cases.
Nick Hurd, the policing minister, said the same techniques seen at RTS may have occurred at Trimega between 2010 and 2014.
The Ministry of Justice has not yet found any affected civil cases affected, but the results may also have been used by schools and local authorities making child protection decisions, or by private employers testing of their employees for banned substances.
Mr Hurd said it may never be possible to identify the true number of Trimega customers affected, due to poor record-keeping, and that its samples cannot be retested.
