Why Errors Happen

Common Mistakes: Specimen Collection and Lab Processing

These are the specific ways this task goes wrong on the job — not hypothetical edge cases, but patterns that cause real documentation errors, patient-safety issues, or workflow problems.

1

Reading a rapid test result after its validated window has passed, which can produce a false positive or false negative.

2

Collecting a urine specimen without giving the patient clear clean-catch instructions, leading to a contaminated sample and a need to recollect.

3

Letting a temperature-sensitive specimen sit at room temperature too long before it reaches the lab.

4

Labeling a batch of specimens all at once after collecting several, instead of immediately after each one.

How the Quality Checkpoints Prevent These

Every mistake above is caught by one of this task's quality checkpoints — the habit of checking these consistently is what actually prevents the error, not just knowing it exists.

  • ✓

    Container and labeling match the patient and are applied immediately, not after the specimen sits unlabeled.

  • ✓

    Point-of-care tests are read within their validated time window, not early or late.

  • ✓

    Outside-lab specimens are stored and transported at the correct temperature for that specific test.

  • ✓

    Biohazard waste is disposed of per protocol, not mixed with regular trash.
