One possible approach would be to use a relative change in creatinine (e.g. threefold) as the primary criterion, with an absolute cutoff (e.g. 4 mg/dL or about 350 mcmol/L) as a secondary criterion when baseline creatinine is abnormal. Similar approaches have been used in the literature (25,26).
The combined sales tax rate for Charleston, SC is 8.5%. This is the total of state, county and city sales tax rates. The South Carolina state sales tax rate is currently 6%. The Berkeley County sales tax rate is 0%. Charleston sales tax rate is 1%.
While South Carolina does not have one of the highest general sales tax rates, when the state sales tax is combined with South Carolina's local, county, and hospitality taxes the total can amount to a maximum general sales tax of 9%. The majority of South Carolina's 46 counties charge a local sales surtax.
