Urohematin is a term used in clinical chemistry to refer to the pigment found in urine. It is spelled as /jʊərəʊˈhiːmətɪn/ in IPA phonetic transcription. The first syllable is pronounced as "yoo-ra" with a schwa sound in the second syllable. The "he" in the third syllable is pronounced with a long "e" sound while the fourth syllable "ma" is pronounced as "mi". Lastly, the "tin" in the last syllable is pronounced with a schwa sound.

Urohematin is a noun that refers to a reddish-brown pigment found in urine, specifically in the form of granules or crystals. It is the final breakdown product of hemoglobin, which is the protein responsible for carrying oxygen in red blood cells.
Derived from the Greek words "ouron" meaning urine and "haima" meaning blood, urohematin is formed during the process of heme degradation. When red blood cells die or are broken down, heme is released and subsequently broken down into its constituent parts, one of which is urohematin.
The presence of urohematin in urine is often indicative of certain medical conditions or pathologies. Urine may appear darker or have a reddish-brown color due to the presence of urohematin, which can be caused by factors such as increased breakdown of red blood cells or the presence of certain substances in the urine.
Laboratory tests that analyze the composition of urine may detect urohematin as part of their analysis, allowing healthcare professionals to assess the patient's health and diagnose potential conditions. Analyzing the concentration and characteristics of urohematin in urine can provide valuable information related to kidney function, blood disorders, or urinary tract issues.
In summary, urohematin is a pigment found in urine that results from the breakdown of hemoglobin. Its presence can indicate various medical conditions, and its analysis is a significant aspect of urine evaluation in clinical settings.
The urinary pigment, supposed to be the same as hematin, which gives varying color to the urine according to its varying degrees of oxidation.

The word "urohematin" is derived from two components: "uro-" and "-hematin".
1. "Uro-" is a combining form derived from the Greek word "ouron", meaning urine. It is commonly used in medical terminology to refer to something related to the urinary system or urine.
2. "-Hematin" is a combining form derived from the Greek word "haima", meaning blood. It is commonly used in medical terminology to refer to a component or derivative of blood.
Therefore, "urohematin" can be understood as a compound term combining "uro-" (related to urine) and "-hematin" (related to blood), possibly indicating its association with a substance or process involving both urine and blood.
