ABOUT INFECTIOUS DISEASE RAPID TESTS
Rapid diagnostic tests are designed to detect specific markers associated with an infection and provide results much faster than many traditional laboratory tests.
Depending on the product, rapid tests may detect antigens, antibodies, or genetic material associated with infectious organisms. Testing methods, sample types, accuracy, intended users, and interpretation requirements vary considerably between products.
Our collection may include tests for COVID-19, influenza A/B, RSV, Group A Streptococcus (strep throat), HIV, and other infectious diseases, subject to product availability and Canadian regulatory authorization.
Always check the individual product page and package labeling to determine its authorized intended use.
KEY BENEFITS
• Rapid results, often within minutes depending on the test
• Convenient screening and diagnostic-support options
• At-home and professional-use products available, depending on authorization
• Individual and bulk-pack options for different testing needs
• Tests for common respiratory and other infectious diseases
• Clear manufacturer instructions for specimen collection and interpretation
• Products sourced from established diagnostic manufacturers
WHO IT’S IDEAL FOR
Depending on the specific test and its authorized intended use, rapid testing may be useful for:
• Individuals experiencing symptoms of a respiratory infection
• Families seeking convenient at-home testing options
• Healthcare professionals and clinics
• Pharmacies and other healthcare settings
• Workplaces and organizations with appropriate testing programs
• Individuals who may have been exposed to a particular infection
• People who need timely information to help determine appropriate next steps
Not every rapid test is authorized for self-testing. Some products are intended only for use by healthcare professionals or trained operators.
WHAT ARE INFECTIOUS DISEASE RAPID TESTS?
Rapid tests use a biological sample—such as a nasal or throat swab, saliva, oral fluid, or small blood sample—to look for specific markers associated with an infection.
Different technologies answer different questions.
Antigen Tests
Antigen tests detect specific proteins associated with an infectious organism.
They are commonly used for respiratory infections because they can provide relatively quick results.
Antibody Tests
Antibody tests detect the body’s immune response to an infection rather than directly detecting the infectious organism.
Because antibodies take time to develop, these tests are not interchangeable with antigen or molecular tests.
Molecular Tests
Molecular diagnostic tests detect genetic material from a virus, bacterium, or other organism.
Some molecular technologies can provide rapid results, although performance and equipment requirements vary substantially by product.
RESPIRATORY RAPID TESTS
COVID-19 Rapid Tests
COVID-19 rapid antigen tests detect proteins associated with SARS-CoV-2.
Depending on the authorized product, testing may be intended for:
• Symptomatic individuals
• Certain asymptomatic screening situations
• At-home self-testing
• Professional point-of-care use
A negative antigen result does not always rule out infection, particularly early in an illness.
Influenza A & B Tests
Rapid influenza tests may help detect influenza A and/or B.
Some newer products combine influenza and COVID-19 testing into a single test, providing more information from one specimen.
RSV Tests
Respiratory syncytial virus (RSV) tests are designed to detect RSV infection.
RSV can affect people of all ages but can be particularly important in infants, young children, older adults, and individuals with certain underlying health conditions.
Multiplex COVID-19, Flu & RSV Tests
Multiplex tests are designed to detect more than one respiratory pathogen from a single sample.
Depending on the product, one test may differentiate among:
• SARS-CoV-2
• Influenza A
• Influenza B
• RSV
Always confirm exactly which pathogens the individual test is authorized to detect.
STREP THROAT RAPID TESTS
Rapid Group A Streptococcus tests are designed to detect Group A Streptococcus (GAS) associated with strep throat.
Because many sore throats are caused by viruses rather than bacteria, appropriate testing can help healthcare professionals determine whether further evaluation or treatment may be required.
A rapid test result should be interpreted according to the manufacturer’s instructions and applicable clinical guidance.
HIV RAPID & SELF-TESTS
Authorized HIV self-tests and point-of-care tests can provide an important option for increasing access to HIV screening.
HIV tests differ in what they detect and have a window period, meaning a recent infection may not yet produce a detectable result.
A reactive screening result is not by itself a definitive HIV diagnosis and requires appropriate confirmatory testing and healthcare follow-up.
If recent HIV exposure is a concern, seek professional advice about appropriate testing timing and whether post-exposure prophylaxis (PEP) may be indicated.
OTHER INFECTIOUS DISEASE TESTS
Depending on availability and Canadian authorization, professional diagnostic products may also exist for infections such as:
• Hepatitis
• Helicobacter pylori
• Malaria
• Other bacterial, viral, or parasitic infections
Some of these products are intended strictly for laboratories or healthcare professionals and should not be represented as consumer at-home tests unless specifically authorized for that purpose.
RAPID TEST FORMATS
Lateral Flow Tests
One of the most common rapid-testing technologies. A sample is processed according to the kit instructions and applied to a test device, where visible control and test indicators may appear.
Rapid Immunoassays
These detect specific antigens or antibodies and may use cartridges, cassettes, strips, or dedicated instruments.
Rapid Molecular Tests
These detect pathogen genetic material using nucleic-acid amplification technologies.
They may offer greater analytical sensitivity in certain applications but can require specialized equipment.
Multiplex Tests
Designed to detect or differentiate multiple pathogens using a single collected sample.
HOW TO CHOOSE THE RIGHT RAPID TEST
Before purchasing, consider:
• What infection you need to test for
• Whether the test is authorized for self-testing or professional use
• Appropriate age range
• Required specimen type
• Testing window or recommended timing
• Result time
• Storage requirements
• Package quantity
• Whether repeat testing is recommended
• Whether a positive or negative result requires follow-up testing
For Canadian customers, verify the regulatory status and intended use of the specific device, rather than assuming an entire test category or brand has the same authorization.
HOW TO USE A RAPID TEST
Instructions vary by product, so always follow the supplied manufacturer’s directions precisely.
In general:
- Read the complete instructions before beginning.
- Wash and dry your hands.
- Collect the required specimen exactly as instructed.
- Process and apply the specimen using the supplied components.
- Start timing according to the manufacturer’s instructions.
- Read the result only within the specified interpretation window.
- Confirm that the control indicator is present.
- Follow the recommended next steps for your result.
Reading a test too early or too late can produce an incorrect interpretation.
UNDERSTANDING RAPID-TEST ACCURACY
No diagnostic test is 100% accurate.
Two important measures are:
Sensitivity — how effectively a test identifies people who have the condition.
Specificity — how effectively a test identifies people who do not have the condition.
Performance can also be affected by:
• Timing of testing
• Quality of specimen collection
• Amount of pathogen present
• Symptoms and stage of infection
• Improper storage
• Incorrect test procedure
• Reading results outside the specified time window
For this reason, a negative rapid test does not always exclude infection.
WHAT TO DO AFTER A NEGATIVE RESULT
A negative result should be interpreted in the context of symptoms, exposure history, and the instructions for the specific test.
Depending on the infection and product, repeat testing or laboratory testing may be recommended.
If you remain symptomatic or have significant exposure despite a negative result, follow applicable healthcare guidance rather than relying solely on one rapid test.
WHAT TO DO AFTER A POSITIVE RESULT
Follow the instructions supplied with the test and current public-health or healthcare guidance applicable to the infection.
Depending on the condition, next steps may include:
• Contacting a healthcare professional
• Confirmatory testing
• Treatment assessment
• Taking precautions to reduce transmission
• Informing appropriate close contacts when recommended
A rapid test should support—not replace—appropriate medical evaluation.
FAQ
Are all infectious disease rapid tests Health Canada approved?
No. Regulatory status is product-specific. Before purchasing, confirm that the particular test is authorized for sale in Canada and review whether it is authorized for self-testing, point-of-care use, or professional use.
Are rapid tests as accurate as laboratory tests?
It depends on the test and infection. Some rapid molecular tests can provide excellent performance, while antigen tests may be less sensitive than laboratory molecular testing in certain circumstances.
Can I use an infectious disease rapid test at home?
Only if the specific product is authorized and labeled for self-testing. Professional-use diagnostic devices should be used according to their authorized instructions.
Can a negative COVID-19 or flu test rule out infection?
Not always. Testing too early or when pathogen levels are low can result in a false-negative result. Follow the test instructions regarding repeat testing and medical follow-up.
Can one rapid test detect COVID-19 and influenza?
Yes, certain combination tests can detect and differentiate COVID-19 and influenza A/B. Some multiplex tests may also include RSV.
Does a positive HIV self-test mean I definitely have HIV?
A reactive HIV screening test requires appropriate confirmatory testing. Follow the product instructions and contact a healthcare professional or testing service for follow-up.
Are rapid tests reusable?
Most disposable rapid-test devices are single-use only. Never reuse a test unless the manufacturer specifically states otherwise.
How should rapid tests be stored?
Storage requirements vary. Follow the temperature and storage conditions printed on the package and do not use a test beyond its authorized expiry date.
CAUTIONS & WARNINGS
• Read all instructions before collecting a sample
• Check the expiry date before use
• Confirm that packaging and test components are intact
• Follow required storage conditions
• Never reuse a single-use test
• Do not substitute one specimen type for another
• Do not interpret results outside the specified reading window
• Keep test components away from young children
• Follow appropriate disposal instructions
• Do not use a negative result to ignore significant or worsening symptoms
Seek urgent medical care for severe symptoms such as difficulty breathing, severe chest pain, confusion, loss of consciousness, significant dehydration, or other signs of medical emergency.
