Specimen Container Types

A specimen container is a sterile, single-use vessel for collecting and transporting a biological sample; a urine collection container is a non-sterile vessel sized for a timed or volume-based urine sample. The two are not interchangeable: sterility, cap type and volume differ by intended test.

Specimen container (sterile) Urine collection container
Sterility Sterile (individually wrapped) Non-sterile
Typical volume 90 mL / 120 mL 120 mL / 4 oz / 3,000 mL (24-hour collection)
Cap Screw cap with a leak-proof seal Screw cap (some with an integrated cup)
Intended use Microbiology culture, swab elution, body-fluid transport Routine urinalysis, 24-hour collection
Suitable for culture Yes No — non-sterile; would contaminate the culture

Which one each test requires

  • Culture / microbiology — a sterile container is required.
  • Routine urinalysis / quantitative urine — a urine collection container is sufficient.
  • 24-hour collection — a 3,000 mL capped collection container, with preservative per the laboratory's instructions.

Frequently asked questions

Can I use a urine cup for a microbiology sample?

No — urine cups are non-sterile and will contaminate a culture.

What is the difference between a specimen container and a urine collection container?

Sterility, cap design and volume; see the table above.

How much urine does a 24-hour collection require to be stored in?

A dedicated 3,000 mL collection container, per the laboratory's instructions.
