  2. Urine urea nitrogen - Wikipedia

    en.wikipedia.org/wiki/Urine_urea_nitrogen

    UUN is determined from 24-hour urine collection. Along with UUN, values for BUN, protein content of diet, enteral or parenteral nutrition, and notable outputs other than urine (gastric residual, fistula output, drainages) are needed to calculate nitrogen balance. Nitrogen Balance = Protein intake/6.25- (UN + 4*) * For average loss via sweat and ...

  3. Nitrogen balance - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_balance

    Nitrogen loss occurs largely through urine in the form of urea, as well as through faeces, sweat, and growth of hair and skin. Blood urea nitrogen and urine urea nitrogen tests can be used to estimate nitrogen balance.

    In highly concentrated urine they may shrivel and develop a spiky shape, which is termed crenation, while in dilute urine they can swell and lose their hemoglobin, creating a faint outline known as a ghost cell. A small quantity of red blood cells in the urine is considered normal.

    Urine also contains antibodies, which can be used in diagnostic antibody tests for a range of pathogens, including HIV-1. [35] Urine after four months of storage (note the color and turbidity change compared to fresh human urine). During storage, the urea in urine is rapidly hydrolyzed by urease, creating ammonia.

  6. Renal urea handling - Wikipedia

    en.wikipedia.org/wiki/Renal_urea_handling

    Urea allows the kidneys to create hyperosmotic urine (urine that has more ions in it - is "more concentrated" - than that same person's blood plasma). Preventing the loss of water in this manner is important if the person's body must save water in order to maintain a suitable blood pressure or (more likely) in order to maintain a suitable ...

    en.wikipedia.org/wiki/Urine_test

    A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]

  9. Urea - Wikipedia

    en.wikipedia.org/wiki/Urea

    The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
