Vitamin B1 (Thiamine), Blood, LC/MS/MS

The Vitamin B1 (Thiamine), Blood, LC/MS/MS test contains 1 test with 1 biomarker.

Brief Description: The Vitamin B1 blood test, also known as Thiamine blood test, measures the level of Vitamin B1 (thiamine) in the blood. Vitamin B1 is a water-soluble vitamin essential for converting food into energy and maintaining proper nerve function. It plays a vital role in carbohydrate metabolism and the functioning of the nervous system.

Collection Method: Blood Draw

Specimen Type: Blood

Test Preparation: Overnight fasting is recommended

When and Why the Vitamin B1 Blood Test May Be Ordered:

A healthcare provider may order a Vitamin B1 blood test for several reasons, including:

1. Thiamine Deficiency: The test is primarily used to diagnose Vitamin B1 deficiency. A deficiency in Vitamin B1 can lead to a condition known as beriberi, which can manifest as neurological symptoms (Wernicke-Korsakoff syndrome) or cardiovascular symptoms (dry or wet beriberi).

2. Alcohol Use Disorder: Chronic alcohol consumption can lead to malnutrition and deficiency of various vitamins, including Vitamin B1. The test may be ordered for individuals with alcohol use disorder to assess their thiamine levels.

What the Vitamin B1 Blood Test Checks For:

The Vitamin B1 blood test measures the concentration of thiamine in the blood. It provides valuable information about a person's Vitamin B1 status, indicating whether they have sufficient levels of the vitamin or are deficient.

Other Lab Tests That May Be Ordered Alongside the Vitamin B1 Blood Test:

When a Vitamin B1 test is ordered, it's often part of a broader evaluation of nutritional status, neurological health, and metabolic function. Here are some tests commonly ordered alongside it:

1. Complete Blood Count (CBC):

   • Purpose: To evaluate overall blood health, including red and white blood cells, and platelets.
   • Why Is It Ordered: To assess for signs of anemia or other hematological abnormalities that can occur with nutritional deficiencies, including thiamine deficiency.

2. Vitamin B6 and Vitamin B12 Levels:

   • Purpose: To measure the levels of other B vitamins.
   • Why Is It Ordered: To assess overall B vitamin status, as deficiencies often occur together and can have similar symptoms.

3. Folate (Folic Acid) Level:

   • Purpose: To measure the level of folate in the blood.
   • Why Is It Ordered: Folate, another B vitamin, works in conjunction with thiamine in many metabolic processes, and its deficiency can mimic or compound thiamine deficiency symptoms.

4. Magnesium Level:

   • Purpose: To measure magnesium in the blood.
   • Why Is It Ordered: Magnesium is important for thiamine metabolism, and deficiency in magnesium can affect thiamine levels.

5. Liver Function Test:

   • Purpose: To assess liver health.
   • Why Is It Ordered: To evaluate liver function, as the liver is involved in thiamine storage and metabolism. Liver dysfunction can affect thiamine levels.

6. Blood Glucose and Hemoglobin A1c (HbA1c):

   • Purpose: To measure blood sugar control over time.
   • Why Is It Ordered: To assess for diabetes or pre-diabetes, conditions in which thiamine metabolism may be altered.

7. Electrolyte Panel:

   • Purpose: To measure key electrolytes in the blood.
   • Why Is It Ordered: To assess overall electrolyte balance, which can be disrupted in severe cases of thiamine deficiency.

8. Lactate and Pyruvate Levels:

   • Purpose: To measure the levels of lactate and pyruvate in the blood.
   • Why Is It Ordered: Elevated levels can be a sign of impaired cellular energy metabolism, potentially related to thiamine deficiency.

These tests, when ordered alongside a Vitamin B1 test, provide a comprehensive assessment of nutritional status and can help diagnose and manage conditions related to thiamine deficiency, such as beriberi or Wernicke-Korsakoff syndrome. They are crucial for identifying the root cause of symptoms related to thiamine deficiency and for guiding appropriate nutritional supplementation and treatment. The specific combination of tests will depend on the individual’s symptoms, dietary intake, risk factors, and overall health status.

Conditions or Diseases That Would Require a Vitamin B1 Blood Test:

The Vitamin B1 blood test is primarily ordered to investigate and diagnose thiamine deficiency, which can be caused by various factors, including:

1. Poor Diet: A diet lacking in foods rich in thiamine can lead to deficiency.

2. Chronic Alcohol Use: Alcohol interferes with the absorption and utilization of thiamine, leading to a higher risk of deficiency.

3. Malabsorption Syndromes: Certain medical conditions affecting nutrient absorption in the gastrointestinal tract may lead to thiamine deficiency.

How Health Care Providers Use the Results of a Vitamin B1 Blood Test:

Healthcare providers use the results of the Vitamin B1 blood test to:

1. Diagnose Thiamine Deficiency: Low levels of Vitamin B1 indicate deficiency and guide appropriate treatment, such as Vitamin B1 supplementation or dietary changes.

2. Monitor Treatment: For individuals with diagnosed thiamine deficiency, the test helps healthcare providers assess the effectiveness of treatment and adjust the dosage if necessary.

3. Assess Nutritional Status: The Vitamin B1 blood test is a valuable tool in assessing a person's overall nutritional status and potential risk of certain conditions related to thiamine deficiency.

Most Common Questions About the Vitamin B1 Blood test:
