Well, currently the only commercially marketed drug test for JWH-018 and JWH-073 is an LC/MS analysis offered by Redwood Toxicology. There are no commercially available immunoassay (e.g. 5-panel) type tests for these cannabinoids as yet, so the urinanalysis must be done by LC/MS or GC/MS in all cases, so is more expensive to perform. Redwood claim that the cut-off for detection is around 72 hours after last consumption, though it's not entirely clear how they've reached that figure. It may vary quite a bit around that value depending on personal metabolism, the amounts used and how frequently it is used. It's still too early days in its testing history to know the true sensitivity limits and person-to-person variability of the test they have developed. That's not to say their results are flawed; the test is built around detection of multiple drug metabolites and is therefore quite robust. I'd imagine these cannabinoids may persist for up to a week or more for a habitual heavy user.
There is currently no commercial test at all for WIN-55,212-2. Under exceptional circumstances a thorough MS analysis of urine or blood could be performed in which WIN-55,212-2 could be identified. This would be very expensive, so would likely only be done under exceptional circumstances.
