parietal pleura. The serous membrane that lines the chest cavity; it extends from the mediastinal roots of the lungs and covers the sides of the pericardium to the chest wall and backward to the spine. The visceral and parietal pleural layers are separated only by a lubricating secretion.
The allowableerror is the target value Â± 10%. Using theexample above, the serum cholesterol targetvalue was 200 mg/dL. The total error is 200mg/dL x 0.1 = 20 mg/dL and the acceptabletotal error limits is 180 to 220 mg/dL.First, always determine if within run isacceptable.
Total allowable error is 20 mg/dLat 200 mg/dL, so the systematic error isacceptable, but inaccuracy consumes nearlyall of allowable error!The final criteria of acceptable methodperformance is total error. Total error is ameasure of systematic plus random errorand should be less than the CLIA total errorlimit.
