Pancreatitis: REF
ALT - In this setting, a threefold or greater elevation of alanine transaminase has a positive predictive value of 95% for acute gallstone pancreatitis.
CRP - High levels of C-reactive protein are associated with pancreatic necrosis.
PCR - Hepatitis C is identified by antibody detection or polymerase chain reaction testing.

ALT - Persistent alanine aminotransferase elevations are consistent with Hep C infection. (REF)

When B-type natriuretic peptide (BNP) > 400 pg/ml CHF likelihood is 95% (REF)

B-type natriuretic peptide (BNP) reliably predicts LV dysfunction on echo. (REF)

LSH/FSH > 3 and elevated DHEA are associated with PCOS.

Alcoholics with recurrent pancreatitis may have normal serum amylase levels; in such cases, serum lipase would be a better test. REF
