Prices are $4.00 per bushel for corn and $9.25 per bushel for soybeans. These prices are relatively optimistic compared to 2016 fall delivery bids, which are near $3.70 per bushel for corn and $8.70 per bushel for soybeans. Note that very low prices are not needed to induce the need to cut costs.
The blood uric acid test measures the amount of uric acid in a blood sample. Uric acid is produced from the natural breakdown of your body's cells and from the foods you eat. Most of the uric acid is filtered out by the kidneys and passes out of the body in urine.
Blood metabolites In addition to THC, blood tests can detect cannabinoid metabolites. Not uncommonly, labs report levels of THC-COOH, the same non-psychoactive metabolite found in urine. As shown in Fig.ix subjects (24%) had detectable blood THC after seven days at levels ranging from 0.2 to 1.5 ng/ml (that is, 0.4 to 3.0 ng/ml in serum) [ Karschner ]. There have been anecdotal reports of even higher day-after blood THC levels in chronic users, but these haven't been confirmed in controlled studies.
