Deceiving proteins! A case of lymphoma and high creatinine
Estimation of kidney function by measuring serum creatinine is one the commonest laboratory tests conducted in clinical practice. Enzymatic methods are often used to measure serum creatinine. Clinicians should be aware of the limitations of these methods, such as test interference with paraproteins.We present a case of falsely elevated serum creatinine in a patient referred for renal biopsy. Th...
متن کاملAn alternative approach for detecting interferences in enzymatic acetaminophen assays.
We read with interest the recent description of yet another case of bilirubin-related positive interference in an enzymatic colorimetric assay for acetaminophen (1 ). As a remedy, these authors suggest measuring bilirubin before every acetaminophen assay and removing it by ultrafiltration when the bilirubin concentration is higher than the reported cutoffs for interference. An alternative and p...
متن کاملFalse positive acetaminophen concentrations in icteric serum
INTRODUCTION Serum concentrations of acetaminophen are measured to predict the risk of hepatotoxicity in cases of acetaminophen overdose and to identify acetaminophen use in patients with acute liver injury without a known cause. The acetaminophen concentration determines if treatment with N-acetyl cysteine, the antidote for acetaminophen poisoning, is warranted. DESCRIPTION A 49-year-old wom...
متن کاملComparison of Two ELISA Methods for the Laboratory Diagnosis of Acute Leptospirosis
Background: Leptospirosis is the most common zoonosis widespread in tropical and temperate countries with low social-economic status. We aimed to compare an ELISA kit with an in-house ELISA assay to test the serum samples of the patients who were suspicious of leptospirosis according to their clinical symptoms. Methods: A total of 282 serum samples of patients suspicious of leptospirosis admitt...
متن کاملMonoclonal paraprotein may interfere with the Roche direct HDL-C Plus assay.
To the Editor: We report here the observation of a falsely decreased HDL-cholesterol (HDL-C) result obtained with the Roche HDL-C Plus assay (polyethylene glycol-modified enzymes, sulfated -cyclodextrin, and dextran sulfate; cat no. 1930648) in an asymptomatic 78-year-old woman (1 ). The total cholesterol of the patient was 3.2 mmol/L, the triglycerides were 1.3 mmol/L, and the HDL-C was suppre...
