Acoustic separation of a test sample

A method comprising:

• determining a value based on a hematocrit of a test sample comprised of plasma and red blood cells;
• applying acoustic waves to a fluidic channel containing the test sample to separate the plasma from the red blood cells, at least one of an amplitude, a frequency, or a duration of the acoustic waves applied to the fluidic channel being based on the value;
• performing optical detection on the plasma;
• and
• determining hemolysis of the test sample based on a result of the optical detection.

A system comprising:

• a detector configured to detect a value that is based on a hematocrit of a test sample comprised of plasma and red blood cells;
• a fluidic channel configured to hold the test sample;
• an acoustic transducer configured to apply acoustic waves to the fluidic channel to separate the plasma from the red blood cells in the fluidic channel;
• and
• a control system configured to control the acoustic transducer to produce acoustic waves that sweep over a range of frequencies, the range of frequencies being based on the hematocrit.
