    Here are some options:

    1. If a result seems unlikely or suggests a serious health issue, a doctor may order a second test to verify or refute the original result.

    2. If there is a health issue that is being address ( high A1C, high cholesterol, low iron, etc.) the only way to see if the treatment is working is to retest the blood at intervals.  It could be 3 months or six months.

    Lots of reasons.  You are always allowed to ask them.

    There are two kinds of testing results that are not valid:  false negative and false positives.  It is common for an MD to reorder a test that comes out positive just to assure that the results are not false positives.  And the reason for that second opinion is I think obvious.  It would be expensive, worrisome, and time wasted to pursue a treatment of some malady when the patient in fact did not have that malady.

    For several reasons, but establishing a trend is one of them--you dont know if a single test is going up (getting worse) or down (better), or falsely negative or positive even,  or responding to treatment, or a number of things, depending on the exact test.
