February 2025—Verichem Laboratories has announced the availability of multilevel clinical reference materials intended for the calibration and calibration verification of acetaminophen and salicylate assays on a wide array of diagnostic testing systems. The materials come in a ready-to-use, liquid-stable format that incorporates the serum-like reactivity of a protein-based matrix with the gravimetric accuracy of an absolute standard. The kit contains 5.0 mL of material at six concentration levels and has a shelf life of 18 months when stored at 2° to 8°C. The product also contains ethanol and lactate to determine the calibration verification of these assays.
The company also offers an extensive line of liquid-stable, ready-to-use biosynthetic clinical reference materials for urine chemistry assays. The multilevel materials include albumin, calcium, chloride, creatinine, magnesium, phosphorus, potassium, sodium, total protein, urea nitrogen, and uric acid.
