Valproic Acid Serum

• Test Name: Valproic Acid Serum Test
• Test Type: Therapeutic drug monitoring test
• Specimen Required: Blood sample (serum)
• Methodology: Immunoassay or chromatography
• Purpose: Measures the concentration of valproic acid in the blood to ensure therapeutic levels are maintained and to avoid toxicity.

• Therapeutic Monitoring: Ensures that the valproic acid levels are within the therapeutic range for effective treatment.
• Dose Adjustment: Helps in adjusting the dosage of valproic acid to achieve optimal therapeutic levels.
• Toxicity Prevention: Identifies potentially toxic levels of valproic acid to prevent adverse effects.
• Compliance Check: Assesses patient adherence to prescribed valproic acid therapy.

• Components:
  • Test kit with necessary reagents.
  • Instructions for sample collection and handling.
  • Calibration standards and quality control materials.
• Procedure:
  • Collection of a blood sample from the patient.
  • Processing of the sample to obtain serum.
  • Analysis of serum using immunoassay or chromatography to determine valproic acid concentration.

• Therapeutic Range: 50-100 µg/mL – Indicates effective therapeutic levels.
• Subtherapeutic Levels: <50 µg/mL – May indicate insufficient dosage.
• Toxic Levels: >100 µg/mL – Indicates risk of toxicity and potential adverse effects.
• Clinical Correlation: Results should be interpreted in conjunction with clinical symptoms and other diagnostic information.

• Quantitative: Provides a numerical value for the concentration of valproic acid.
• Units: Results are typically expressed in micrograms per milliliter (µg/mL).
• Reference Range: Therapeutic, subtherapeutic, and toxic ranges established for clinical interpretation.
• Turnaround Time: Typically within 1-2 days, depending on the laboratory.

Q. What is the Valproic Acid Serum Test?
The Valproic Acid Serum Test measures the concentration of valproic acid in the blood to monitor therapeutic levels and avoid toxicity
 

Q. Why is the Valproic Acid Serum Test ordered?
