Abstract: | Abstract: "Hygia" cowside milk progesterone kit examined Milk samples of a wide range of progesterone concentrations (< 0.6 – 50 ng/ml) were analyzed with the cowside test "Hygia" (Hartmann AG, HeidenheirnlBrenz). The test is easy to conduct and takes 10–15 min. In case of high (> 10 nglml), intermediate (2.2–9.5 ng/ml) and low (< 1.8 ng/ml) progesterone levels correct diagnoses were arrived at in 98%, 87% and 95% of all cases, respectively. |
