> To guard against false positives, the Mandatory Guidelines for Federal Workplace Drug Testing Programs, published in 2017, require a codeine cutoff of 2,000 nanograms per milliliter of urine. But the Hackensack University Medical Center's lab, according to Kate's complaint, used a cutoff of 300 ng/ml, less than one-sixth the federal standard. Virtua Voorhees Hospital's lab, according to Kaitlin's complaint, used a cutoff of just 10 ng/ml, 99.5 percent lower than the recommended level. This makes them look pretty negligent.
