The KACEY Anti-Freeze EG /OX Combo Test Strips measures the presence of both ethylene glycol and oxalate in a plasma sample. A drop of plasma (10uL) is placed onto each of the two the test pads on the test strip. After waiting the required 10 minutes the color that forms in the test pad on the strip is compared to a color chart to determine both the presence and concentration of the ethylene glycol and oxalate in mg/dl. The Level of Detection (LOD) starts at 10 mg/dl and is effective in determining Ethylene Glycol Poisoning in both cats and dogs. See package insert for complete product details.
