What do RUQ, LUQ, RLQ, and LLQ designate?

They designate Abdominal Quadrants. The abdomen is divided by two perpendicular planes that intersect at the navel, creating four regions: upper-right, upper-left, lower-right, and lower-left. This system helps localize organs and symptoms quickly. For example, the liver and gallbladder are mainly in the upper-right quadrant; the stomach and spleen in the upper-left; the appendix in the lower-right; parts of the colon in the lower-left. Other terms like abdominal regions describe a different subdivision, and “quadrant planes” or “quadrapoint zones” aren’t the standard labels used.
