Sample Required:
This test requires a 24-hour urine sample. You will be provided with a container to collect all urine produced over a 24-hour period.
Test Time:
The results for a Porphobilinogen (PBG) Quantitative Urine 24 H test are typically available within a few days to a week, depending on the laboratory’s processing time.
Test Normal Range:
The normal range for PBG in a 24-hour urine sample is typically less than 4 milligrams per deciliter (mg/dL).
What is the Test?
The Porphobilinogen (PBG) Quantitative Urine 24 H test measures the level of PBG in a 24-hour urine sample. PBG is a substance involved in the synthesis of heme, a component of hemoglobin, which is essential for oxygen transport in red blood cells. Elevated PBG levels can indicate a group of rare genetic disorders called porphyrias.
Test Procedure:
Discard the first morning urine and note the time. Collect all urine produced over the next 24 hours in a provided container. Keep the container in a cool place, as instructed. Return the sample container to the laboratory or healthcare provider as soon as the collection period is complete.
When to Take the Test:
A PBG Quantitative Urine 24 H test is typically ordered when there is suspicion of porphyria, a group of rare inherited disorders that affect the nervous system or skin. Symptoms may include abdominal pain, neurological issues, or skin problems.
Who Should Take This Test:
Individuals who have symptoms suggestive of porphyria or those with a family history of porphyria may be recommended to take this test. It is also used for monitoring and managing known cases of porphyria.
Precautions for Exceptional Cases (Pregnancy, etc.):
There are no specific precautions related to pregnancy for this test. However, it’s essential to inform your healthcare provider if you are pregnant or have any medical conditions that may affect the test results.

Q3: Can medications or diet affect the results of this test?
A: Yes, certain medications and dietary factors can affect PBG levels. It’s essential to inform your healthcare provider about any medications or dietary supplements you are taking.
Q4: How should I store the 24-hour urine sample?
A: Keep the collection container in a cool place, preferably a refrigerator, during the 24-hour collection period. Avoid exposure to direct sunlight or extreme temperatures.
