That is a good thing IMO, some who are flirting with cobalt may have to be a bit more careful.

(k) Cobalt at a concentration at or below 100 micrograms per litre in urine or 25 micrograms per litre in plasma

In the article recently linked by Trish, I noticed that mg/l urine would seem to be far more reliable

In a study where different laboratories across the globe tested the same samples, the variation between testing laboratories was as high as 82% for the testing in serum and 23% in urine. Because of the greater agreement between lab testing methods using urine, the international community has settled on a urine threshold of 100 mcg/mL raceday threshold for uniformity.
