Final answer:
Cholesterol and Uric Acid are the specimens least likely to require special handling as they are stable in blood samples at room temperature and do not need protection from light or immediate cooling. The correct option is A.
Step-by-step explanation:
Specimens that are least likely to require special handling are Cholesterol and Uric Acid. Cholesterol is a common test and is stable in blood samples at room temperature for several hours.
Uric acid, while less soluble than substances like ammonia or urea, is also stable under routine handling conditions.
Unlike specimens such as bilirubin, folate, gastrin, lactic acid, homocysteine, and renin, cholesterol and uric acid do not require protection from light or immediate cooling and can typically be handled under normal laboratory conditions without rapid degradation or alteration. The correct option is A.
