VITAMIN B6 (PYRIDOXAL PHOSPHATE)

The Pyridoxal Phosphate (PLP) test measures the active form of vitamin B6 in the blood and provides a direct indicator of your vitamin B6 status. PLP is a coenzyme involved in amino acid metabolism, neurotransmitter synthesis, hemoglobin formation and homocysteine regulation, so accurate measurement helps assess nutritional adequacy and metabolic function. This home-based test is suitable for convenient sample collection across Dubai and the UAE and is useful in evaluating nutritional, liver and kidney-related disturbances that affect B6 metabolism.

Clinically, PLP measurement is used to diagnose or monitor deficiency and to guide supplementation, especially in people with neuropathy, unexplained anaemia, malabsorption, chronic liver or renal disease, or those taking medications that interfere with B6 (for example isoniazid or certain anticonvulsants). Results can help your physician tailor dietary, supplement or treatment decisions and detect both deficiency and excessive intake that may contribute to neurological symptoms. Home collection is performed by trained staff and results are reported with local reference ranges and professional interpretation recommendations for follow-up in the UAE healthcare setting.
