Acetest

Acetest

 [as´ĕ-test]
trademark for a reagent tablet containing sodium nitroprusside, aminoacetic acid, dibasic sodium phosphate, and lactose, turning a purple color in the presence of ketone bodies in urine, blood, plasma, or serum; the intensity of the color reaction indicates the acetoacetate or acetone concentration, ranging from a pale lavender through a dark purple as the concentration increases.

Acetest

A brand name for a tablet used to test for ketones in urine and other fluids.

Se han utilizado, ademas, otras pruebas como la razon grasa: proteina, al igual que varios equipos portatiles (cow-side test) que permiten hacer el diagnostico en campo, obteniendo resultados inmediatos y a menor costo como la determinacion de la concentracion de [beta]HB en sangre completa (Precision Xtra meter, Optium Exceed), o en leche (Ketolac [beta]HB) o la determinacion semicuantitativa de acetoacetato en orina (Ketostrix, Acetest) y leche (Ketostix, Pink Test).
Acetest and Ketostix (Ames Co.) are semiquantitative tests that are widely used to measure acetoacetate and acetone.
Urine ketones were confirmed with Acetest and bilirubin was confirmed with Ictotest (Bayer Corp, Elkhart, Indiana).
Similarly, 2 of 8 responding laboratories were still using Acetest to confirm urine ketones.
Many laboratories use semiquantitative nitroprusside-based assays to rapidly measure ketones (e.g., Acetest).
Acetest, Ictotest, spun hematocrits (if you even do them anymore--we do not), a few tube and slide typing tests in blood bank, perhaps a few of the species differentiating tests in micro, Wright's stain, Gram's stain.
It can also be used for confirmatory tests such as Acetest, Clinitest, Ictotest reagent tablets, and refractometry.
In the absence of GC testing for isopropanol, the "Acetest" may be used as an insensitive surrogate because there is some reactivity of this reagent toward acetone.
Q The instructions for reading Bayer Acetest tablets results list the results as small, medium, or large.
The presence of mesna in these specimens was suggested by false-positive ketone reactions with Chemstrip 10UA and Acetest. When the specimens were tested with Rapignost (visual reading), false-positive reactions developed in both the ketone and ascorbic acid pads; furthermore, the intensity of false-positive ketone reactions directly correlated with the intensity of apparently false-positive ascorbic acid results (Table 1).
Many labs use Acetest tablets for testing serum acetone.
