intermediate test result, valid inconclusive test result
An indeterminate diagnostic test result can be defined as a result that adds no additional diagnostic information to the original (pre-test) likelihood of having the condition, so that the test result does not alter the likelihood of having the condition. An intermediate test result can be defined as a result that adds some diagnostic information, but less than either a positive or negative test result. However, these terms are not used consistently and may be used interchangeably.
