Bloom System�
The Bloom System is a medical testing system. It provides screen-
ing and monitoring of target markers and medical guidance. It
combines lateral fl ow assay-based bodily fl uid testing (Bloom Test
strips), an established diagnostics technology, with an electronic
reader for test strip analysis (Bloom Lab) and user-friendly
software for displaying and interpreting results (the Bloom App).
2.2. Bloom Ferritin Test
2.2.1. Principle of the method
The Bloom Ferritin Test strip is a rapid immunochromatographic
assay based on gold nanoparticles. When the blood is mixed with
the provided dilution buff er and applied onto the test strip, the
diluted blood fl ows along the test strip and binds to anti-Ferritin
antibodies, which detect the ferritin in the blood and will create a
color line detected by the Bloom Lab. The Bloom Ferritin Test strip
also includes a control line, which will be detected by the Bloom
Lab to verify whether the test has run correctly. Users will receive
their results in the form of a report via the Bloom App.

Unusually high titers of heterophile antibodies or rheumatoid
factor (RF) in the blood may aff ect the test results.
