Why do doctors need to repeat blood tests?
Is it just to double check?

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.
