Bulk Pregnancy Tests: What to Verify Before You Order

Bulk pregnancy tests: the FDA class, the label items the FDA guidance expects, and a receiving and expiry checklist for a large lot.

Written and maintained by CASRAI Editorial Board

Last updated

Short answer: before ordering bulk pregnancy tests, confirm four things on the supplier’s documents: that the product is an over-the-counter hCG urine test cleared by the FDA for its intended use, that the package insert states an expiration statement, a maximum time to read the result and what the control checks, and that the stated accuracy is not above 99%. Then check each delivered lot against the same label.

This page is general product and regulatory information for staff who buy and receive supplies. It is not medical advice and does not replace the manufacturer’s instructions for use.

What bulk pregnancy tests are

A bulk pregnancy test order is a large lot of qualitative urine hCG tests, usually strips, cassettes or midstream sticks. They detect human chorionic gonadotropin (hCG), a placental hormone. Under 21 CFR 862.1155(a), an hCG test system intended for the early detection of pregnancy measures hCG in plasma or urine.

Three roles are easy to confuse when buying in volume:

  • Home or over-the-counter urine tests. The FDA’s guidance on OTC hCG 510(k)s covers these qualitative tests. See HCG test strips for how results are read.
  • Urine tests in a provider’s office. MedlinePlus says urine tests can be done at a provider’s office or at home.
  • Blood tests. MedlinePlus says blood tests are always done in a provider’s office or a lab, and can find very small amounts of hCG.

Clinics that perform tests as part of their services should also read what a CLIA-waived test is, because that is a separate question from FDA clearance of the strip itself.

How the FDA classifies and reviews hCG tests

The regulation splits hCG test systems by intended use. A system intended for the early detection of pregnancy is Class II (21 CFR 862.1155(a)(2)). A system intended for any other use, such as an aid in diagnosing certain tumors, is Class III and needs approval under section 515 of the act (862.1155(b)). The practical consequence for a buyer is that the stated intended use on the product matters: a pregnancy-detection claim sits in the Class II category.

The FDA’s guidance for OTC hCG 510(k)s (issued July 22, 2000) tells manufacturers what to put in a submission and in labeling. It is a public description of what a compliant insert should contain, which makes it a usable yardstick when you compare supplier paperwork.

What the label must tell you: a supplier-document checklist

The table below turns the FDA guidance into questions you can ask a supplier. Each row cites the guidance or regulation it comes from.

Ask the supplier for What the FDA source says
Intended use statement Early detection of pregnancy by measuring hCG in urine or plasma is Class II under 21 CFR 862.1155(a).
Stated sensitivity For qualitative assays, sensitivity (detection limit) is the analyte concentration at which 95% of results are positive.
Accuracy claim Percent accuracy should never exceed 99%, and statements such as “100% accurate” or “virtually 100% accurate” should be avoided.
Earliest-use claim A manufacturer may state the test detects pregnancy by the first day of the missed period and no sooner, unless validated by clinical data.
Maximum read time Stability data should support the maximum time for interpreting the result after it first appears.
Control description If the device has a procedural or design control, its function should be described, for example whether it shows chemicals are working, enough sample was added or the procedure was followed.
Expiration statement Labeling should say the test cannot be reused and must not be used past the expiration date.

A supplier whose marketing claims “100% accurate” is making a statement the FDA guidance says to avoid. For context, MedlinePlus (last updated September 25, 2025) gives 97-99% as the accuracy of urine tests, so a claim above that range deserves a closer look at the paperwork.

Receiving, storage and expiry checks for a large lot

The FDA guidance and MedlinePlus support a short receiving routine. Anything beyond it, such as storage temperature and humidity limits, comes from the manufacturer’s instructions for use for that product, not from a general rule.

  1. Read the expiration date on the carton and on the pouch. Both FDA labeling guidance and MedlinePlus say not to use a test past its expiration date.
  2. Match the insert to the product. Confirm the insert has the read-time limit and control description listed above, and keep one copy with the lot record.
  3. Follow the insert’s storage instructions. Record the lot number and the storage conditions the manufacturer states.
  4. Note the control description. MedlinePlus explains that the control symbol shows the test worked correctly; it does not say whether someone is pregnant. Keep the description from the insert with the lot record.

Organisations that stock tests alongside other client supplies can compare this with the pregnancy resource center supply checklist. For the same expiry-and-label discipline applied to a kit, see the travel medical kit guide.

Common misunderstandings

  • “Bulk” means a different product. A multi-pack is usually the same kind of qualitative test sold in larger counts; the regulatory questions above apply to each product.
  • A higher accuracy claim is better. The FDA guidance says accuracy should never exceed 99% and warns against “100% accurate” language, so an inflated claim is a reason to look harder at the paperwork.
  • The control line is the result. It is not. It shows only that the test worked.
  • Ovulation and pregnancy strips are interchangeable. They detect different hormones. See how to read ovulation test strips for the contrast.

FAQ

What should I check before ordering bulk pregnancy tests?

Check the intended use, the sensitivity statement, the accuracy claim, the maximum read time, the control description and the expiration statement on the insert and supplier documents, using the table above.

Are bulk pregnancy tests the same as clinic tests?

Not necessarily. MedlinePlus describes urine tests used at home or in a provider’s office and blood tests done only in an office or lab. Whether a clinic’s use falls under CLIA waiver is a separate question covered in the CLIA-waived test entry.

Can I trust a “99.9% accurate” claim?

The FDA guidance says percent accuracy should never exceed 99%, so a figure above that is not in line with the guidance.

What does the control symbol on a pregnancy test show?

MedlinePlus says the control symbol shows that the test worked correctly and does not tell you whether someone is pregnant. The FDA guidance expects the insert to describe the function of the internal control, so ask the supplier for that wording.
