Correct Answer is C
Explanation

However, further testing is required to confirm the results and determine the cause of the elevated levels.
Choice A is incorrect because low levels of MSAFP may indicate a risk for Down syndrome, not elevated levels.
Choice B is incorrect because while elevated levels of MSAFP may indicate a risk for neural tube defects, further testing is required to confirm this.
Choice D is incorrect because while repeating the test may be necessary, further testing beyond just repeating the MSAFP screening may also be required.
