BC Powder has historically been most commonly associated with relief of headaches. Many users of the brand erroneously believe the name of the product to be "BC Headache Powder." Recent advertising and marketing endeavors by the company suggest that it is eager to associate itself with relief of general bodily aches and pains as well. Goodys Powder, like BC, is also distributed by Prestige Brands. For many years, singer and actor Faron Young was the celebrity featured on many of the products television and radio commercials. For several years, BCs television and radio commercials have featured real-life users of the product, non-actors who are encouraged to submit their stories to BC Powder through contests announced on radio programs. Recently, most entries have been culled from listeners of the Charlotte, NC-based radio program The Big Show with John Boy and Billy. In recent years, members of the Tom Joyner Radio Shows audience have appeared in BC commercials after hearing of the promotion on that program, or from promotions held on Joyners annual "Fantastic Voyage" fantasy cruise. BC Powder also distributes and markets BC Cherry and BC Arthritis Formula. In a deal which took effect in 2012, GlaxoSmithKline (GSK) sold BC Powder and 16 other brands to Prestige Brands. References

The D-xylose test involves having a patient drink a certain quantity of D-xylose, and measuring levels in the urine and blood; if there is no evidence of D-xylose in the urine and blood, it suggests that the small bowel is not absorbing properly (as opposed to problems with enzymes required for digestion).The gold standard for detection of bacterial overgrowth is the aspiration of more than 105 bacteria per millilitre from the small bowel. The normal small bowel has less than 104 bacteria per millilitre. Some experts however, consider aspiration of more than 103 positive if the flora is predominately colonic type bacteria as these types of bacteria are considered pathological in excessive numbers in the small intestine. The reliability of aspiration in the diagnosis of SIBO has been questioned as SIBO can be patchy and the reproducibility can be as low as 38 percent. Breath tests have their own reliability problems with a high rate of false positive. Some doctors factor in a patients response to treatment as part of the diagnosis. Breath tests have been developed to test for bacterial overgrowth. These tests are either based on bacterial metabolism of carbohydrates to hydrogen, methane, or hydrogen sulfide, or based on the detection of by-products of digestion of carbohydrates that are not usually metabolized. The hydrogen breath test involves having the patient fast for a minimum of 12 hours then having them drink a substrate usually glucose or lactulose, then measuring expired hydrogen and methane concentrations typically over a period of several hours.
