i have been wondering why blood tests have to be so expensive? See [1]

Once the human person has interacted in drawing the blood, then a few drops might be needed to do some additional tests, like check for adequate Vitamin D, etc that the doctor did not prescribe, but is still useful to know, and can be an upsell, there should be just a marginal cost to automated machines/processes doing that test.

A further improvisation is to be able to track a person's details like past history, current complaints, and make a recommendation to add a few additional tests for a few dollars each?
