The aim of this study is to overview diagnostic tests for ketosis in dairy cows, including laboratory and cowside tests. Measurement of blood BHB values in blood is the gold standard test for the diagnosis of ketosis. The most commonly used cut points for SCK are ≥ 1.2 mmol/L or ≥1.4 mmol/L, and for clinical ketosis are about 3.0 mmol/l, for BHB in the blood. The cowside blood BHB test using a hand-held meter (ketometer) has higher levels (above 95%) of sensitivity and specificity than other cowside tests, and can replace laboratory blood BHB testing. The cowside milk (BHB) test (a Ketolac BHB test strip with a cut-point of ≥200 μmol/L of BHB in milk) is a potentially useful tool for routine herd monitoring for SCK in early lactation dairy cows.
