One machine performed 8,400 tests a week and it is estimated that 10% to
15% "were inaccurate".
Adaltis has installed more than 2,500 of these Labotech machines, which
can perform up to eight blood tests simultaneously, according to the
company's Web site.
2,500 x 8,400 divided by 15% (faulty tests) =
Up to 3,150,000 faulty tests a week

Rep. Elijah Cummings, D-Md., said a congressional hearing will be held in
May to look into the equipment and its use.
"Every patient that took their test there — their trust was completely
betrayed," said Turner, who now lives in a Southeastern state that she
declined to identify. "People should be able to trust that when they go
somewhere, they are going to get the right results."

This figure is based on a bucketload of speculations.

Maryland General, an affiliate of the University of Maryland
Health System (UMMS), issued HIV and hepatitis test results to
more than 450 patients even though the readings on laboratory
instruments indicated those results might be inaccurate.
The machine warned them of problems and they ignored the warning.
Edmond F. Notebaert, UMMS president, said retests have been
offered to about 2,100 patients, two patients who originally
tested negative for HIV tested positive in the retests and three
who had tested negative for hepatitis tested positive.
All or almost all of the test results the machine warned about were
correct anyway.

You quote the president of the company making the machines. Very
convincing.....not.
The fact there is an offical enquiry says it all.

In May, we held our initial hearing to look into allegations, first
reported by the Baltimore Sun in March, that Maryland General Hospital
released more than 450 invalid HIV and hepatitis test results from
June 2002 to August 2003, despite error messages from the testing
instrument indicating that the results might be incorrect.
...
Sadly, the case of Maryland General appears to be one in which
laboratory supervisors not only failed to ensure that proper quality
controls were in place but also deliberately altered or concealed
information that would have led to the discovery of invalid test
results being released to patients.
