Table 4 Accuracies calculated for each laboratory based on 3-HPMA fortified samples at 400 ng/ml (samples 2), 1200 ng/ml (samples 3), and 3600 ng/ml (samples 4)

From: An inter-laboratory comparison of urinary 3-hydroxypropylmercapturic acid measurement demonstrates good reproducibility between laboratories
