So if the girl tested positive for cocaine, with a reading of 5000 and the machine can read a minimum of 500, she had 10 times the minimum amount in her system?From this image, I found the device they are likely using.

Then using FDA's website:

I also found the device the one above superseded.

Here is their cocaine test, an EIA test.

The cutoff for their devices are indeed 5ng/10ml or 500pg/ml.

Tables. ng/10mg of hair.

Or pg/mg (1 milligram) of hair.

So if Minnesota Monitoring Inc. was using one of Psychemedics' devices, the default reading appears to be ng/10mg or pg/mg. This does make sense concerning the hair required.
That sounds like a lot. Is 5000 pictogram/milliliters something that can be converted to a layman's unit of understanding?
