Digitoxin Quantitative, Serum or Plasma
Also known as: DIGIT SP
Use
Digitoxin Quantitative, Serum or Plasma test is used to optimize drug therapy and monitor patient adherence. It provides a quantitative measure of digitoxin levels in serum or plasma, helping clinicians assess whether a patient is maintaining therapeutic levels of the drug. Monitoring is essential as digitoxin has a narrow therapeutic range, and deviations can lead to suboptimal therapy or toxicity.

Results may be affected by improper specimen handling or collection beyond the specified time frame. Separators tubes are an unacceptable condition for specimens, and results are dependent upon proper sampling and storage conditions.
