1. reexamination; retest; follow-up test (especially medical)
Running a test, measurement, or examination a second time, usually to confirm an abnormal result, monitor a change, or double-check a decision. Most often heard in medical contexts — for example, after a health check-up returns borderline numbers — but also used for inspections and technical tests in general.
来月(らいげつ)再検査(さいけんさ)()ける
I will have a follow-up test next month.
Based on the health check-up results, I was told I needed a follow-up test.
Because there was an abnormality in the blood values, the doctor ordered a follow-up test.
Because a defect was found in the factory's products, a reexamination was carried out on all the lots.

Composed of the prefix (さい) (again, re-) + 検査(けんさ) (inspection, examination, test). Appears most frequently in the medical phrase 再検査(さいけんさ)()ける (to undergo a follow-up test), since Japanese annual health check-ups routinely flag borderline values and ask the patient to come back for confirmation.

Common collocations

Verbal use

The word can take する to act as a verb: 再検査(さいけんさ)する — to reexamine, to retest. In that form, the subject is the one doing the checking: 医者(いしゃ)数値(すうち)再検査(さいけんさ)した (the doctor retested the values). In patient-side usage the passive-like 再検査(さいけんさ)()ける is much more common.

Usage

Beyond medicine, you will encounter the word in quality control (factory inspections, food safety), academic contexts (retaking a test), and engineering (retesting equipment). In all these uses, it keeps the core sense of "checking again."
