Final answer:
The enzyme method of Benedict testing is accurate but requires expensive equipment, making it less accessible for some users.
Step-by-step explanation:
A disadvantage of the enzyme method of Benedict testing is that it requires expensive equipment. This type of analysis involves using enzyme-linked assays such as enzyme-linked immunosorbent assay (ELISA), wherein specific enzymes are used to catalyze reactions that result in a detectable color change.
Although highly accurate and efficient, these types of methods can be cost-prohibitive due to the specialized equipment and reagents necessary for the tests.
