Biotinidase is an enzyme that helps release biotin from proteins, allowing the body to absorb and utilize it effectively.
The Biotinidase Quantitative Test is a diagnostic procedure used to measure the activity of the enzyme biotinidase in the blood. Biotinidase is an enzyme that plays a critical role in the metabolism of biotin (a form of vitamin B7), which is essential for several biological processes, including the breakdown of fats, carbohydrates, and proteins. This test is especially significant in detecting biotinidase deficiency, a rare genetic disorder that can lead to various health issues if left untreated.
The Biotinidase Quantitative Test is typically conducted by collecting a blood sample from the patient, often through a venipuncture (insertion of a needle into a vein, typically in the arm). In some cases, a heel stick may be used, especially in newborn screening programs. The blood sample is then sent to a laboratory, where it is analyzed for the activity level of biotinidase.
The test measures the amount of biotinidase enzyme present and compares it to normal reference levels. If the enzyme activity is below the expected range, it may indicate a biotinidase deficiency. In some cases, further testing may be required to determine whether the deficiency is partial or profound.
Symptoms of biotinidase deficiency can vary significantly depending on the severity of the condition. Early signs, often occurring in the first few months of life, may include:
1] Severe skin rash or dermatitis
2] Hair loss
3] Neurological issues such as seizures, muscle weakness, or developmental delays
4] Hearing and vision problems
If left untreated, biotinidase deficiency can lead to more severe neurological issues, including cognitive impairment, and may even be life-threatening. However, with early diagnosis and biotin supplementation, most symptoms can be prevented or reversed.
The results of the Biotinidase Quantitative Test will indicate the level of biotinidase activity in the blood. A normal result suggests that the enzyme is functioning properly, and there is no biotinidase deficiency. A low level of enzyme activity may indicate biotinidase deficiency, which is classified into:
1] Partial deficiency: Some enzyme activity remains, but it may still require biotin supplementation.
2] Profound deficiency: Very little or no enzyme activity, requiring immediate treatment with biotin supplementation.
If a deficiency is confirmed, biotin supplementation (usually in the form of biotin pills or injections) is typically prescribed. Biotin therapy is highly effective and, when started early, can prevent the onset of severe symptoms.

Yes, the Biotinidase Quantitative Test is often part of newborn screening in many countries, as early detection of biotinidase deficiency can prevent serious complications. Newborns diagnosed with biotinidase deficiency are typically started on biotin supplementation shortly after birth.
This test is performed to diagnose biotinidase deficiency, a rare genetic condition that can lead to symptoms such as skin rashes, hair loss, developmental delays, and neurological problems like seizures. Early detection through the Biotinidase Quantitative Test allows for timely treatment with biotin supplementation, preventing or alleviating symptoms.
The Biotinidase Quantitative Test is a simple blood test. A small sample of blood is drawn, typically from a vein in the arm. The blood is then analyzed in a laboratory to measure the level of biotinidase enzyme activity. The test is quick and minimally invasive.
The Biotinidase Quantitative Test is a low-risk procedure. The most common risks are those associated with any blood draw, such as mild discomfort, bruising, or infection at the needle site. Serious complications are rare.
