Validity of purulent vaginal discharge, esterase, luminometry, and bacteriological tests for diagnosing uterine infection in dairy cows
The laboraty test was the most accurate for detecting uterine infections in dairy cows, but it is not practical on farms. A simpler method called luminometry may be a useful alternative.

Validity of luminometry and bacteriological tests for diagnosing intramammary infection at dry-off in dairy cows
Laboratory and on-farm bacterial tests were fairly accurate at detecting udder infections in dairy cows before dry-off. However, a simpler test called luminometry did not perform well and isn’t reliable for this purpose.

Accuracy of leukocyte esterase test, endometrial cytology and vaginal discharge score for diagnosing postpartum reproductive tract health status in dairy cows at the moment of sampling, using a latent class model fit within a Bayesian framework
Vaginal discharge score (≥ mucus with flecks of pus) had the highest sensitivity and specificity for diagnosing reproductive tract disease in dairy cows. Leukocyte esterase (≥ moderate amount of leukocytes) had similar accuracy than endometrial cytology (≥ 6% neutrophils). Mean within-herd prevalence of reproductive tract disease was estimated at 47.9%.
