Homework / test English to Italian Science Biology (-tech,-chem,micro-) BioArray Solutions HEA BeadChip Kit

Si tratta di Summary of the test
...
BeadChips are read with the BioArray Solutions Array Imaging System™ (AIS™ 400C) with assay results interpreted, analyzed and reported through the BioArray Solutions Information System (BASIS™) software. The AIS system captures the fluorescent signal from individual beads in an image of the entire array. It also detects the average signal intensity, coefficient of variance of the intensities, and number of beads measured for each type of probe. The BASIS software then imports the raw intensity output, assesses the validity of the internal controls, and generates assay results.

Non sono del settore e non ho mai tradotto testi di questo genere, per cui pur trovando materiale in rete, non capisco se bead qui si lascia in inglese e soprattutto che cos'è.
Grazie.
