A new screening test called FingerChol has been developed to diagnose hyperlipidaemia with a point-of-care finger-prick test. To evaluate the effectiveness of the test, 200 participants aged 50 and above are screened with the FingerChol test. These patients also undergo the gold-standard test (formal lipid profile blood test) for comparison.
The results obtained are shown in the table below:
Hyperlipidaemic Not hyperlipidaemic
Positive FingerChol test 60 40
Negative FingerChol test 20 80
What is the positive predictive value of the FingerChol test for this population?
