Description
Quantitative detection of the SARS-CoV-2 spike protein in exosomes
This blood test measures the SARS-CoV-2 spike protein contained within exosomes isolated from plasma or serum.
Exosomes are very small particles naturally released by cells. They act as a communication system in the body, transporting biologically active substances such as proteins and genetic material between cells and organs.
Research has shown that SARS-CoV-2 spike protein can be packaged into exosomes and transported through the bloodstream. This allows the spike protein to reach different tissues and organs, including those with a higher density of receptors for the spike protein.
For this test, exosomes are purified from approximately 4 mL of plasma or serum.
While the test detects the presence of spike protein, it cannot identify the specific source, such as a viral variant or vaccination
The detection of SARS-CoV-2 spike protein in exosomes is considered an indication of a systemic distribution and effect of the spike protein within the body.
It is recommended that this test is interpreted alongside SSP2
