Obtain a 7-mL blood serum sample in a red-top tube.

Serum is preferred over plasma for testing.

Running samples in duplicate is recommended.

Polystyrene ELISA plates or high-sensitivity plates are preferred.

Cardiolipin should be diluted in ethanol. [5]

Control samples should be collected from at least 40 healthy young (< 50 years) people to determine the local cutoff for the above tests.
