Differential Diagnosis for Nước Tiêu Màu Xanh Lá Cây (Green Urine)
- Single Most Likely Diagnosis
- Medication effect (e.g., methylene blue, indigo carmine, or certain antibiotics like ciprofloxacin): Certain medications are known to cause a change in urine color, including turning it green, due to their chemical properties and how they are metabolized and excreted by the body.
- Other Likely Diagnoses
- Food or dye ingestion: Consuming foods or substances with strong dyes (like green food coloring) can temporarily change the color of urine.
- Urinary tract infection (UTI) with specific bacteria: Although less common, certain bacteria can produce pigments that alter urine color.
- Do Not Miss Diagnoses
- Porphyria: A group of disorders that can lead to the accumulation of porphyrins, which may cause urine to turn a variety of colors, including green, upon exposure to sunlight.
- Liver disease: Certain liver conditions can affect the metabolism of bilirubin and other substances, potentially leading to changes in urine color.
- Rare Diagnoses
- Melanogenuria: A rare condition where melanin is present in the urine, potentially causing color changes.
- Alkaptonuria: A genetic disorder affecting the metabolism of tyrosine and phenylalanine, leading to the accumulation of homogentisic acid, which can cause urine to darken upon standing but is less likely to cause a green color directly.
- Pseudomonas infection: Pseudomonas aeruginosa can produce pigments like pyocyanin, which gives a blue-green color, but this is more commonly associated with infections in cystic fibrosis patients or in certain types of wounds rather than a direct cause of green urine.
