&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;OVERVIEW&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;The Pyridoxal 5-Phosphate (PLP) test in plasma measures the levels of this active form of vitamin B6 in the blood. PLP is essential for various biochemical processes, including amino acid metabolism and neurotransmitter synthesis. Abnormal levels of PLP can indicate vitamin B6 deficiency or metabolic disorders, which may manifest as neurological symptoms, anemia, or other health issues. This test helps in diagnosing such conditions and monitoring the effectiveness of vitamin B6 supplementation or treatment, guiding adjustments to ensure proper metabolic function and overall health.&lt;/span&gt;&lt;/p&gt;
