About this service

Carnitine Quantitative Profile by Flow Injection Analysis–Tandem Mass Spectrometry (FIA-MS/MS) is an advanced laboratory test used to measure carnitine levels in a blood sample. Carnitine is a vital compound that plays a crucial role in metabolism by helping transport fatty acids into the mitochondria for energy production. This analysis is considered a valuable tool for diagnosing and monitoring metabolic disorders related to carnitine deficiency, such as primary and secondary carnitine deficiency, which may lead to symptoms like chronic fatigue and muscle weakness. The FIA-MS/MS technique provides highly accurate measurement of carnitine, allowing determination of free carnitine levels and related compounds. Due to its accuracy and efficiency, this test is recommended for patients with unexplained symptoms related to energy and metabolism, as well as for newborns when there is a family history of metabolic disorders.

Purpose Test

Free Carnitine: The active form that helps transport fatty acids into mitochondria for energy production.
Acetylcarnitine: Another form of carnitine involved in metabolism and can indicate certain disorders.
Total/Bound Carnitine: Reflects levels of carnitine-bound compounds.
Diagnose metabolic disorders: Detect primary and secondary carnitine deficiencies affecting the body’s ability to use fat for energy.
Identify causes of symptoms: Such as chronic fatigue, muscle weakness, or exercise intolerance.
Monitor treatment: Track patients receiving carnitine therapy to ensure levels return to normal.
Assess overall health: Provide comprehensive insight into metabolic or energy-related issues.

Recommended groups

Individuals with symptoms of carnitine deficiency: Such as chronic fatigue, muscle weakness, or exercise intolerance.
Newborns: Recommended for babies showing unexplained symptoms or with a family history of metabolic disorders.
Patients with chronic diseases: Such as kidney or liver patients, where treatment may affect carnitine levels.
People on strict diets: Such as low-fat diets or prolonged fasting.
Athletes: To assess carnitine levels as part of their diet or training regimen.
Cardiac patients: Those with heart conditions, as carnitine plays a key role in heart health.
Individuals with a family history of metabolic disorders: Testing is recommended in families known to have metabolic disturbances.
Patients receiving carnitine therapy: To monitor treatment response and ensure levels return to the normal range.

Symptoms indicative

Chronic fatigue: Feeling persistent tiredness or excessive exhaustion without a clear reason.
Muscle weakness: Difficulty performing daily activities or reduced muscle strength, especially after physical activity.
Exercise intolerance: Rapid fatigue or inability to sustain effort during workouts or physical activities.
Muscle pain: Unexplained muscle aches, particularly after physical activity.
Cardiac issues: Such as irregular heartbeats or chest pain.
Concentration difficulties: Problems focusing or feeling confused.
Unexplained weight loss: Weight loss without attempting or unusual changes in appetite.
Family history: Presence of a family history of metabolic disorders or carnitine deficiency.

Normal Levels

Free Carnitine: 20 to 50 µmol/L
Acetylcarnitine: 10 to 25 µmol/L
Total Carnitine: The sum of free and acetylcarnitine, which should fall within the laboratory-recommended range
Levels below 20 µmol/L: May indicate carnitine deficiency, affecting the body’s ability to use fats for energy.
Levels above 50 µmol/L: May indicate an abnormal condition or metabolic disorder.

Frequently Asked Questions

Short answers to the FAQs published with this service.

What is the Carnitine Quantitative Profile Test?

It is a test used to measure the levels of carnitine and its different forms in the blood, helping diagnose metabolic disorders related to carnitine deficiency.

How is the test performed?

A blood sample is taken from a vein and sent to the laboratory to measure carnitine levels using FIA-MS/MS technology.

Preparations required?

No special preparations are usually required, but inform your doctor about any medications or supplements you are taking.

Normal carnitine levels?

Normal levels vary slightly by lab, but generally, free carnitine in the blood ranges from 20 to 50 µmol/L.

When to take this test?

Recommended for people with symptoms of carnitine deficiency, such as chronic fatigue or muscle weakness, or those with a family history of metabolic disorders.

Potential risks of blood draw?

Risks are rare, but may include mild pain or bruising at the puncture site.

Can the test diagnose other conditions?

Although primarily used to diagnose carnitine deficiency, abnormal levels may indicate other metabolic-related conditions.

How are results interpreted?

Results should be interpreted by a specialist doctor, considering medical history and symptoms.

Follow-up for abnormal results?

If results are abnormal, the doctor may recommend additional tests or a comprehensive evaluation to identify the exact cause.
