Use
The Sulfonamides, Quantitative, Serum or Plasma test is used to optimize drug therapy and monitor patient adherence to sulfonamides. Quantitative analysis helps in ensuring the therapeutic levels of the drug in the body, minimizing toxicity, and assessing patient compliance.
Special Instructions
This test is performed by a non-ARUP laboratory and requires careful specimen handling to avoid pre-analytical errors. Collect specimens in plain Red, Lavender (K2 or K3EDTA), or Pink (K2EDTA) tubes and separate from cells as soon as possible or within 2 hours of collection. Transfer the serum or plasma to an ARUP Standard Transport Tube.
Limitations
The test result is nonspecific and may include multiple sulfonamides, metabolites, and other cross-reactive substances. The presence of interfering substances like acetaminophen, benzocaine, lidocaine, furosemide, thiazide diuretics, and para-aminobenzoic acid can affect the identity and quantity of the reported results.
