A healthy glow, better skin texture, and increased energy are all reported by many patients
The evaluating clinician, not the patient, not the platform, makes the determination of whether therapy is appropriate
Simple tasks, like taking a shower or walking to the mailbox, can trigger a cascade of debilitating symptoms known as post-exertional malaise (PEM)
Calculate the percentage of l-carnitine derivative (R ) from the derivatized Sample solution: Result = r L /(r L + r D ) 100 r L = peak response of the l-carnitine derivative from the derivatized Sample solution r D = peak response of the d-carnitine derivative from the derivatized Sample solution Calculate the corrected percentage of l-carnitine (C 7 H 15 NO 3 ) (C ) in the portion of Levocarnitine taken: Result = (R L P B )/(P A P B ) 100 R L = percentage of l-carnitine derivative, calculated previously P A = percentage of ()-FLEC as determined for (+)-1-(9-Fluorenyl)ethyl chloroformate solution P B = percentage of (+)-FLEC as determined for (+)-1-(9-Fluorenyl)ethyl chloroformate solution Calculate the corrected percentage of d-carnitine in the portion of Levocarnitine taken: Result = 100 C L C L = corrected percentage of l-carnitine, calculated previously Acceptance criteria: NMT 0.2% of d-carnitine Limit of Potassium [NoteThe Standard solution and the Sample solutions may be modified, if necessary, to obtain solutions of suitable concentrations adaptable to the linear or working range of the instrument.] Standard solution: 31.25 g/mL of potassium in water, prepared from potassium chloride previously dried at 105 for 2 h Sample stock solution: 0.625 mg/mL of Levocarnitine in water Sample solution A: Transfer 20.0 mL of the Sample stock solution to a 25-mL volumetric flask, and dilute with water to volume
