- Helps diagnose porphyria and related disorders.
- Assists in evaluating liver function.
- Detects lead exposure in the body.
- Monitors treatment effectiveness for porphyria.
- Provides a comprehensive overview of porphyrin levels.
Who Should Consider the Test
People experiencing unexplained abdominal pain, skin sensitivity to sunlight, or neurological symptoms might find this test beneficial. For example, someone with recurring skin rashes after sun exposure could gain valuable information from this test.
Consider ordering this test if you experience:
- Unexplained abdominal pain.
- Skin sensitivity to sunlight.
- Neurological symptoms like confusion or seizures.
- Family history of porphyria.
- Unusual urine color changes, which might indicate porphyrin issues.
Ordering this test can help pinpoint the cause of these symptoms, leading to targeted treatment. Delaying the test might result in prolonged symptoms and delayed diagnosis.

Labs Included When Ordering Your Porphyrins, Fractionated, Quantitative, 24-Hour Urine Test
| Test Name | Reference Range | Significance of Biomarker | High and Low Levels of Biomarker |
|---|---|---|---|
| Uroporphyrin I | 4.1-22.4 | Uroporphyrin I is a type of porphyrin involved in heme production. Elevated levels can indicate disruptions in this pathway. | High: High levels of Uroporphyrin I may suggest porphyria or liver dysfunction.
Low: Low levels of Uroporphyrin I are typically not clinically significant. |
| Uroporphyrin III | 0.7-7.4 | Uroporphyrin III is another porphyrin variant essential in the heme synthesis pathway. Abnormal levels can reflect metabolic issues. | High: High levels of Uroporphyrin III may indicate certain types of porphyria.
Low: Low levels of Uroporphyrin III are generally not a concern. |
| Heptacarboxyporphyrin | ≤3.3 | Heptacarboxyporphyrin is an intermediate in heme biosynthesis. Elevated levels can signal disruptions in this process. | High: High levels of Heptacarboxyporphyrin may be associated with specific porphyrias.
Low: Low levels of Heptacarboxyporphyrin are typically not clinically relevant. |
| Hexacarboxyporphyrin | ≤10 | Hexacarboxyporphyrin is a porphyrin compound in the heme production pathway. Abnormal levels can indicate metabolic disturbances. | High: High levels of Hexacarboxyporphyrin may suggest certain metabolic disorders.
Low: Low levels of Hexacarboxyporphyrin are generally not significant. |
| Pentacarboxyporphyrin | ≤4.6 | Pentacarboxyporphyrin plays a role in heme synthesis. Elevated levels can reflect issues in this pathway. | High: High levels of Pentacarboxyporphyrin may be linked to specific types of porphyria.
Low: Low levels of Pentacarboxyporphyrin are typically not a concern. |
| Coproporphyrin I | 7.1-48.7 | Coproporphyrin I is a porphyrin involved in heme biosynthesis. Abnormal levels can indicate metabolic issues. | High: High levels of Coproporphyrin I may suggest liver dysfunction or porphyria.
Low: Low levels of Coproporphyrin I are generally not clinically significant. |
| Coproporphyrin III | 11.0-148.5 | Coproporphyrin III is another variant in the heme production pathway. Elevated levels can reflect metabolic disturbances. | High: High levels of Coproporphyrin III may be associated with certain porphyrias.
Low: Low levels of Coproporphyrin III are typically not a concern. |
| Total Porphyrins | 35.0-210.7 | Total porphyrins measure the combined levels of various porphyrins in urine. Increased levels can indicate disruptions in heme metabolism. | High: High levels of Total Porphyrins may suggest porphyria or liver dysfunction.
Low: Low levels of Total Porphyrins are generally not a concern. |
According to PubMed, “Porphyrin disorders can lead to a variety of symptoms, including neurological and dermatological manifestations, making timely diagnosis crucial for patient management.”
