Pregnancy Test Kits in Canada vs the US: Which Class Applies?

Quick facts

• A human chorionic gonadotropin test system measures HCG, a placental hormone, in plasma or urine.
• United States: 21 CFR 862.1155 splits by intended use. A system intended for the early detection of pregnancy is Class II; a system intended for any uses other than the early detection of pregnancy — such as an aid in the diagnosis, prognosis and management of treatment of persons with certain tumours or carcinomas — is Class III.
• The Class III limb of that section carries a premarket approval requirement dated to the enactment of the 1976 amendments, and the section states that approval under section 515 is required before the device may be commercially distributed.
• Canada: the device is an in vitro diagnostic device, and Part 2 Rule 9 of Schedule 1 to the Medical Devices Regulations, SOR/98-282 names a near-patient device for the detection of pregnancy or for fertility testing in the Class II row of its table.
• A laboratory-based pregnancy test is Class II under the general IVDD rules, and an HCG test used outside pregnancy — for example in tumour diagnosis or disease staging — moves to Class III.
• Canadian regulation text used here is current to 2026-09-21 and last amended 2026-06-17, as stated on the official consolidation.

A pregnancy test is the one HCG application that everyone recognises, and the two classification systems handle the rest of the analyte very differently. The American code keeps both uses inside a single numbered section and separates them into two classes, one of which has carried a premarket approval requirement since 1976. Canada writes a short carve-out naming the near-patient pregnancy use, and lets the general IVDD rules handle everything else. This article sets out both routes, the near-patient carve-out table, and the record a clinic or laboratory should hold.

What is an HCG test system in each classification system?

The American section is unusual because it is written as two parallel limbs inside one number.

• Limb (a), early detection of pregnancy. The identification paragraph states that an HCG test system intended for the early detection of pregnancy is intended to measure HCG, a placental hormone, in plasma or urine. The classification paragraph states Class II, without qualification.
• Limb (b), any other use. The identification paragraph covers a system intended for any uses other than the early detection of pregnancy, such as an aid in the diagnosis, prognosis and management of treatment of persons with certain tumours or carcinomas, again measuring HCG in plasma or urine. The classification paragraph states Class III, and adds that as of the date of enactment of the amendments, May 28, 1976, an approval under section 515 is required before the device may be commercially distributed.

Canada classifies the system as an IVDD and names one near-patient application directly:

• Part 2 Rule 9, table item 1 — a near patient in vitro diagnostic device for the detection of pregnancy or for fertility testing is classified as Class II.
• Part 2 Rule 4 — an IVDD not covered by the transmissible-agent or patient-management rules and intended for use in diagnosis or patient management is Class II, unless it falls into a listed exception.
• Part 2 Rule 4(a) and (e) — an IVDD intended for use in screening for or in the diagnosis of cancer, or intended for use in disease staging, is Class III.

The Canadian schedule therefore reaches the same split that the American section does, but it reaches it through a named exception rather than through two limbs of one section.

How does the HCG test system class differ between Canada and the United States?

The difference is in how the same analyte is divided, and in how explicitly each system names the ordinary pregnancy use.

Item	Canada	United States
Named entry	None; classified as an IVDD	21 CFR 862.1155
Early pregnancy detection, near patient	Class II, named in the Part 2 Rule 9 table	Class II, limb (a) of the section
Early pregnancy detection, laboratory	Class II under the general IVDD rules	Class II, limb (a) of the section
Tumour or carcinoma use	Class III, through the cancer diagnosis and disease staging exceptions	Class III, limb (b) of the section
Premarket position for the Class III use	Licence class follows the rule	Premarket approval required, with the 1976 date in the section
Basis for the class	The intended use and the setting of use	The intended use, written as two limbs

Two features stand out. The first is that the ordinary pregnancy use is the low-risk limb in both systems, and each system says so in its own way: the American code as a separate classificatory paragraph, the Canadian schedule as a named row in the near-patient table.

The second is that the non-pregnancy uses of the same analyte are treated as a genuinely different device in both systems. An HCG assay used in tumour diagnosis or disease staging is Class III on both sides of the border, and in the United States that limb carries a premarket approval requirement rather than an exemption.

Which near-patient devices does Canada name in its table?

The near-patient table in Part 2 Rule 9 is short, and knowing what is and is not in it is the fastest way to predict a Canadian class for a point-of-care test.

Near-patient device	Canada (Part 2 Rule 9)	United States
Detection of pregnancy or fertility testing	Class II	862.1155, Class II for early pregnancy detection
Determining cholesterol level	Class II	Clinical chemistry section, Class II
Microbiology media to identify an organism	Class I	Culture media sections, Class I
Monitoring drugs, substances or biological components	Not in the table; Part 2 Rule 4(f) can lift the device to Class III	Section by analyte, usually Class II
Blood glucose measurement	Not in the table; Part 2 Rule 6 applies, Class III	862.1345, Class II
Coagulation testing	Not in the table; Part 2 Rule 6 applies, Class III	864.7750, Class II

The table is worth reading twice, because it is the shortest path to the Canadian class of a point-of-care test. A device that is in the table takes the class in the table. A device that is not in the table and is intended for use outside a laboratory takes Class III under Part 2 Rule 6.

Do Canada and the United States agree on the non-pregnancy use of an HCG test?

They agree on the class and diverge on the mechanism.

Both systems place an HCG assay used for tumour diagnosis or disease staging in Class III. In the United States that result is written into the same section as the pregnancy use, and the section adds the premarket approval date. In Canada the result comes from the general IVDD rules, where an IVDD used in cancer screening or diagnosis, or for disease staging, is Class III unless a different rule applies first.

For a laboratory that runs HCG for more than pregnancy, the practical consequence is that one assay menu can carry two classes inside one organisation, and the class follows the stated intended use rather than the analyser it is run on. Part 2 Rule 7 reinforces this: where an IVDD including its analysers, reagents and software is intended to be used with another IVDD, the class of both is that of the IVDD in the class representing the higher risk.

A buyer or quality lead who wants to check a specific product can look it up in the openFDA device classification API or the FDA classification database. On the Canadian side the class follows from the rules, and the near-patient table is the first place to look.

What should a clinic or laboratory keep on file for an HCG test system?

Six items, and the first fixes the class.

• The stated intended use of each assay. Pregnancy detection and tumour-related use are different classes in both countries.
• The setting of use. In Canada a near-patient placement brings the Rule 9 table into play; a laboratory placement follows the general rules.
• The licence or clearance position. In Canada, the class and licence status; in the United States, which limb of the section applies.
• The quality control record. Controls, calibration and the interval at which they are run belong with the device file.
• The operator competency record. Where a non-laboratory operator runs the test, the competency record supports the program.
• The result and action log. The record should show what happened when a result fell outside the acceptable range.

Which consumables does a collection bench restock alongside its assay lines?

A specimen collection bench restocks containers, pipettes, transport packaging and disposables on the same cycle as its analysers. For practices buying at case level, the wholesale ordering page sets out account and case terms, and the B2B wholesale collection lists the lines held for institutional buyers. The graduated specimen cups cover sample collection, the laboratory consumables pack with parafilm and pipettes covers bench handling, and programs that also run culture work can start with the sterilization monitoring collection or the biological indicator 5-pack trial.

Frequently Asked Questions

What class is a pregnancy test kit in the United States?

Class II for a system intended for the early detection of pregnancy, under 21 CFR 862.1155. The same section places a system intended for any uses other than early pregnancy detection, such as an aid in the diagnosis of certain tumours or carcinomas, in Class III.

What class is a pregnancy test kit in Canada?

Class II. A near-patient in vitro diagnostic device for the detection of pregnancy or for fertility testing is named in the Class II row of the table to Part 2 Rule 9 of Schedule 1 to the Medical Devices Regulations, and a laboratory-based pregnancy test is Class II under the general IVDD rules.

Why is one section in the United States written as two limbs?

Because the intended use changes the risk. The early detection of pregnancy is a routine determination, while the same hormone measured for tumour diagnosis or disease staging can steer treatment. The section separates the two uses and gives each its own class.

Does the tumour use of an HCG test require premarket approval in the United States?

Yes. The section states that as of the date of enactment of the amendments, May 28, 1976, an approval under section 515 of the Federal Food, Drug, and Cosmetic Act is required before the device described in that limb may be commercially distributed.

What is in the Canadian near-patient table besides pregnancy testing?

Part 2 Rule 9 names near-patient devices for the detection of pregnancy or for fertility testing, and for determining cholesterol level, and places both in Class II. It also lists microbiological media used to identify a microorganism and IVDDs used to identify a cultured microorganism, both in Class I.

Do Canada and the United States class the non-pregnancy use of HCG the same way?

They reach the same class by different mechanisms. Both place the tumour-diagnosis and disease-staging use in Class III. The United States writes that result into limb (b) of section 862.1155 with a premarket approval date, and Canada reaches it through the cancer diagnosis and disease staging exceptions in Part 2 Rule 4.
