Molecular Biology Tests

Some lab tests look directly for tiny pieces of DNA or RNA.

Molecular tests look for very specific genetic material in a sample. This can help a doctor check for selected infections or investigate certain changes in genes. You may have heard of PCR, a common method used for some of these tests.

Sample: depends on the testMethod: selected DNA or RNA checksPreparation: follow the exact collection instructions

2

The sample is collected and handled under specific conditions.

3

The lab looks for the target named in your request.

How to prepare

•

Check which sample is needed before arriving.

•

Mention recent treatment or antibiotics to your doctor.

•

Understanding your result

"Detected" means the test found the target it was designed to look for. "Not detected" does not always rule out a condition, especially if the sample was taken too early or the target level was low.

Frequently asked questions

Is PCR a blood test?+

Not always. PCR can be performed on different sample types, depending on what is being checked.

Does a molecular test check everything in my body?+

No. It looks for the specific target requested.

Is this the same as an antibody test?+

No. Antibody tests usually look at your immune response, while many molecular tests look for DNA or RNA.

Can I collect my own sample?+

Only when the laboratory confirms that self-collection is suitable for that exact test.
