Reddish-orange: Intake of certain medications or other substances. Rusty-yellow to reddish-brown: Intake of certain medications or other substances. Other colors: Various substances ingested in food or drink, particularly up to 48 hours prior to the presence of colored urine. Brief changes in odor are usually merely interesting and not medically significant. Example: the abnormal smell many people can detect after eating asparagus. A urinalysis is frequently ordered during the workup of acute renal failure. Full kidney function can be detected through the simple dipstick method.
Urine K may be ordered in the workup of hypokalemia. In case of gastrointestinal loss of K, the urine K will be low. In case of renal loss of K, the urine K levels will be high. Decreased levels of urine K are also seen in hypoaldosteronism and adrenal insufficiency. This condition is divided into primary and secondary types.
Proteins may be measured with the Albustix test. And also in case of testicular cancer in male. May be present as intact RBCs, which indicate bleeding. RBCs incur mechanical damage during the glomerular passage, and then osmotic damage along the tubules, so get dysmorphic features. Painless hematuria of nonglomerular origin may be a sign of urinary tract malignancy, which may warrant a more thorough cytological investigation. In case of hemoglobinuria, a urine dipstick shows presence of blood, but no RBCs are seen on microscopic examination. The urine color may also be red due to excretion of reddish pigments or drugs.
Although glucose is easily filtered in the glomerulus, it is not present in the urine because all of the glucose filtered is normally reabsorbed from the renal tubules back into the blood. This happens because insulin is necessary for the transport of glucose from the blood into the body cells. The metabolism of fat proceeds in a series of steps. The fixed phagocytic cells of the spleen and bone marrow destroy old red blood cells and convert the heme groups of hemoglobin to the pigment bilirubin. The blood normally contains a small amount of free and conjugated bilirubin. In neonatal screening, a value above the upper limit defines phenylketonuria.
This test detects the ion concentration of urine. If the SG is under 1. In this case, the urinalysis would be designed to detect whatever marker indicates drug use. This breakthrough led to additional dip-and-read tests for proteins and other substances.
The invention was named a National Historic Chemical Landmark by the American Chemical Society in May 2010. The urine is under the cover slide, in the upper segment formed by the H-shaped grooves. Medscape, 12 Causes of Discolored Urine. The University of Texas Southwestern Medical Center at Dallas.
