BP?Blood pressure.

C&S?Culture and sensitivity, a test performed to detect infection.

CBC?Complete blood count.

CC?Chief complaint, the patient?s main concern.

D/C or DC?Discontinue or discharge. For example, a doctor will D/C a drug. Alternatively, the doctor might DC a patient from the hospital.
