Urea is a colorless, crystalline substance when pure. In its solid form, it typically appears as white granules or powder. Urea is also soluble in water and does not have a distinct color in solution. Its lack of color makes it a widely used compound in various applications, including fertilizers and medical products.

What is a positive urea result color?
A positive urea result, typically observed in a urea test, is indicated by a color change to pink or red. This color change usually occurs due to the presence of urease, an enzyme that breaks down urea into ammonia and carbon dioxide, leading to a pH increase. The resulting alkaline environment causes a pH indicator in the test medium to change color, signaling a positive result.
Why the color of urea is yellow?
Urea can turn yellow due to the degradation of urea into ammonia and biuret under certain conditions, such as exposure to high temperatures or alkaline environments. This process can result in the formation of colored compounds, which can give the urea a yellow hue.
What is proteus mirabilis results for urea test?
Proteus mirabilis is positive for the urea test, meaning it can hydrolyze urea, producing ammonia and raising the pH of the medium, causing a color change. This is due to the presence of the enzyme urease in Proteus mirabilis.
What is clinical significant of urea?

Why urea gives green colour to flame test?
Urea itself does not produce a green color in a flame test. However, if urea is contaminated with certain metals, such as copper, it can yield a green flame due to the presence of copper ions. In a typical flame test, metal salts are responsible for the characteristic colors observed, and the green color is specifically associated with the emission spectra of those metal ions when heated.
Is enterococcus faecalis positive or negative with the urea broth test?
It is urease positive .It possesses the enzymes urease which hydrolyses urea to form ammonia. As a result the pH of the medium used for detection of urease enzyme (Urea Broth) increases and shows bright pink colour, since phenol red is bright pink in alkaline conditions.
What color tube is used for urea?
A tiger or gold top tube is typically used for urea testing. It usually contains a clot activator and gel separator that helps in separating serum from the blood cells after centrifugation.
WHAT COLOR IS THE TUBE DRAWN IN FOR A BUN?
The color of the tube used to draw a blood urea nitrogen (BUN) test is typically purple or green. The specific color can vary depending on the laboratory or healthcare facility's protocol.
What colour is your dogs pee?
The urine of a dog, like the urine of most mammals, is a dull yellow color ranging in intensity from a light lemonade color to a darky murky mango fruit yellow. The difference in colors is due to concentration of the dissolved wastes, particularly urea - lighter colors have a lower urea concentration while darker colors have a higher urea concentration. If you notice anything white or blood-red in the urine, or if the urine color shifts outside the spectrum of basically yellow, you should take your dog to a veterinarian for an examination as these color changes can be a sign of intoxication, bladder infection or cancer.
