Pee In A Cup – MUCH Simpler Cancer Test

What your pee color means, according to science

| New method would make it easy to get a cancer test, as there’s no need to draw blood 

| Health24 – A Japanese firm is poised to carry out what it hailed as the world’s first experiment to test for cancer using urine samples, which would greatly facilitate screening for the deadly disease.

Engineering and IT conglomerate Hitachi developed the basic technology to detect breast or colon cancer from urine samples two years ago.

It will now begin testing the method using some 250 urine samples, to see if samples at room temperature are suitable for analysis, Hitachi spokesman Chiharu Odaira told AFP.

“If this method is put to practical use, it will be a lot easier for people to get a cancer test, as there will be no need to go to a medical organization for a blood test,” he said.

It is also intended to be used to detect pediatric cancers.

“That will be especially beneficial in testing for small children who are often afraid of needles,” added Odaira. Read the full story at health24.com. 

Clinical Urine Tests; What Your Pee Color Means

From Wikipedia, the free encyclopedia

Clinical urine tests are various tests of urine for diagnostic purposes. The most common is a urinalysis (UA), one of the most common methods of medical diagnosis.

The word is a portmanteau of the words urine and analysis. Other tests are urine culture (a microbiological culture of urine) and urine electrolyte levels.

The target parameters that can be measured or quantified in urinalysis include naked-eye (gross) examination for color and smell plus analysis for many substances and cells, as well as other properties, such as specific gravity.

A part of a urinalysis can be performed by using urine test strips, in which the test results can be read as color changes. Another method is light microscopy of urine samples.

Target parameters

Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.[3]

In addition to the substances mentioned in tables below, other tests include a description of color and appearance.

Color

The following are examples of color change causes and not a complete listing.

  • Nearly colorless: Excessive fluid intake for conditions; untreated diabetes mellitus, diabetes insipidus, and certain types of nephritis.
  • Yellow: Distinctly yellow urine may indicate excessive riboflavin (vitamin B2) intake.
  • Yellow-amber: Normal.
  • Yellow-cloudy: excessive crystals (crystalluria) and/or excessive pus (pyuria).
  • Orange: Insufficient fluid intake for conditions; intake of orange substances; intake of Phenazopyridine for urinary symptoms.
  • Red: Leakage of red blood cells or of hemoglobin from such cells; intake of red substances.
  • Dark:
  • Reddish-orange: Intake of certain medications or other substances.
  • Rusty-yellow to reddish-brown: Intake of certain medications or other substances.
  • Dark brown: Intake of certain medications or other substances; damaged muscle (myoglobinuria due to Rhabdomyolysis) from extreme exercise or other widespread damage, possibly medication related; altered blood; bilirubinuria; intake of phenolic substances; inadequate porphyrin metabolism; melanin from melanocytic tumors.
  • Brown black to black: Intake of substances or medications; altered blood; a problem with homogentisic acid metabolism (alkaptonuria), which can also cause dark whites of the eyes and dark-colored internal organs and tissues (ochronosis); Lysol (a product that contains phenols) poisoning; melanin from melanocytic tumors). Paraphenylenediamine is a highly toxic ingredient of hair dye formulations that can cause acute kidney injury and result in black urine.[4]
  • Purple due to Purple urine bag syndrome.[4]
  • Magenta to purple-red: Presence of phenolphthalein, a stimulant laxative previously found in Ex-Lax.
  • Green, or dark with a greenish hue: Jaundice (bilirubinuria); problem with bile metabolism. Recent surgery requiring high doses of Propofol infusion. The use of a medication (Uribel) that is similar to phenazopyridine for the relief of urinary symptoms.
  • Other colors: Various substances ingested in food or drink, particularly up to 48 hours prior to the presence of colored urine.
