S.C. Code § 14-9-210
The county solicitor shall prepare and, through the presiding judge of the court of general sessions, submit to the grand jury, while in attendance upon the court of general sessions, bills of indictment in all cases pending in the county court in which the punishment may exceed a fine of one hundred dollars or imprisonment for thirty days, when such cases have not been previously acted on by the grand jury. The grand jury shall act thereon and report its action to the presiding judge of the court of general sessions and said judge shall direct the clerk of the court of general sessions to report the same to the presiding judge of the county court at its next ensuing term. All cases in which bills of indictment are so found shall stand for trial by the county court as though found by the grand jury while in attendance upon the county court.
