САЖЕТАК:
Cilj ovog rada je da opiše načine dijagnostikovanja ketoze, uključujući laboratorijske i brze (cowside) testove. Standardni “zlatni test” za dijagnozu subkliničke ketoze (SKK) kod mlečnih krava jeste laboratorijsko merenje koncentracije beta-hidoksibuterne kiseline (BHB) u krvnom serumu ili krvnoj plazmi. Najčešće korišćene granične vrednosti za dijagnozu subkliničke ketoze jesu vrednosti za BHB u krvi veće od 1,2 mmol/L ili veće od 1,4 mmol/L, dok za kliničku ketozu one iznose oko 3,0 mmol/L. Cowside test za određivanje koncentracije BHB u krvi jeste jednostavni ručni uređaj (ketometar) i može se upotrebljavati na farmi, a ovaj test ima visoki procenat (˃95%) oestljivosti i specifičnosti u odnosu na druge cowside testove i može zameniti laboratorijska ispitivanja u dijagnozi ketoze. Cowside BHB test, odnosno ketolac BHB test trakice sa graničnim vrednostima većim od 200 μmol/L za BHB u mleku je potencijalno korisno sredstvo za rutinski pregled stada mlečnih krava na početku laktacije za dijagnozu ketoze.
