About 3 grams of soluble fiber is needed daily for an effect on cholesterol levels. FDA acknowledges that other sources of beta-glucan soluble fiber and other types of soluble fiber may have similar effects on cholesterol levels. But the agency is awaiting evidence before judging these effects. FDA regulates health claims on food labels to ensure that claims are accurate and don't mislead consumers. Earlier this year, FDA cleared Dr. Brown's Home Drug Testing System, the first nonprescription test system for detecting marijuana, PCP, amphetamines, cocaine, heroin, codeine, and morphine in urine.
Results are available anonymously by identification number.
The system includes a kit to collect and mail a urine sample. Directions for use and for obtaining and interpreting results are also provided. The user labels the urine sample with an identification number provided in the kit and sends it to a specified government-certified laboratory for analysis. The laboratory evaluates the sample for possible tampering, tests it for drugs of abuse, does a confirmation test to minimize false positive readings, and then forwards the results by computer to the manufacturer's results center. To obtain the results, which are available one to three days after the lab receives the urine sample, the user calls a toll-free phone number and provides the sample identification number.
