Final answer:
The fecal occult blood test has waived status under CLIA, while blood typing and complete blood count are not waived due to their complexity and associated risks.
Step-by-step explanation:
The test that is granted waived status under the Clinical Laboratory Improvement Amendments (CLIA) is c) the fecal occult blood test. Tests with waived status under CLIA are those that are considered simple and have a low risk for an incorrect result. Examples of other waived tests include urine pregnancy tests and some HIV screening rapid tests. Blood typing, which is used to determine an individual's blood type, is not a waived test due to its complexity and the potential risks involved if performed incorrectly. Similarly, the complete blood count (CBC), which includes a differential white blood cell count, is a more complex test requiring specific laboratory equipment and trained personnel to interpret the results accurately.
