Measuring the toxicity of chemical compounds

Identifying pathogenic microbes directly from clinical samples

Analysing the genetic makeup of antibodies

Detecting specific antibodies or antigens related to microbial infections

The test is IgM negative, but is positive for IgG: The patient is having an early phase, active COVID-19 infection

The test is negative for both IgM and IgG: The patient has never been infected with COVID-19 or is still in the incubation period

The test is IgM negative, but is positive for IgG: The patient has recently been infected with COVID-19 and now has protection against COVID-19, or has been vaccinated against COVID-19

The test is positive for both IgM and IgG: The body has an active COVID-19 infection and is trying to build up protection against it

The test is positive for IgM, but is negative for IgG: The patient is having an early phase, active COVID-19 infection

The test result indicates the presence of the Neisseria meningitidis (meningococcus) groups A, C, Y or W135 antigen OR N. meningitidis group B in the test sample

The test result indicates the presence of the Haemophilus influenzae type b antigen in the test sample 

The test result indicates the presence of the Streptococcus group B (Strep B) antigen in the test sample

The test result indicates the presence of the Streptococcus pneumoniae antigen in the test sample

The patient is negative for bacterial meningitis and may instead be presenting with symptoms consistent with viral meningitis

The test result indicates the presence of the Neisseria meningitidis (meningococcus) groups A, C, Y or W135 antigen in the test sample. N. meningitidis group B is not present.

A POSITIVE result is inconclusive and requires further testing to determine infection status

A POSITIVE result confirms the presence of IgG antibodies, which are specific for Influenza B Virus

A POSITIVE result indicates a past infection with Influenza B Virus

A POSITIVE result suggests a current or recent infection, as IgM is typically the first antibody produced during a new infection

The presence of the target antibody in the specimen

The absence of the target antibody in the specimen

The presence of non-specific antibodies that may cross-react with other antigens

The presence of the target antigen in the specimen

Antibodies are present but do not bind to the antigens

The presence of specific antibodies in the sample

Clumping is due to a test error, not a true antibody-antigen reaction

No antibodies are present in the sample

Identifying specific antibodies in patient serum

Measuring antibody levels to assess vaccination status

Detecting microbial antigens in clinical samples

Determining bacterial cell morphology under a microscope

To separate serum proteins from the antigen of interest

To produce a detectable signal in the presence of enzyme-labeled antibodies

To label the antibodies in the patient's serum sample

To bind with antigens in the patient's sample
