Methods of Metrology Processing of Qualitative and Quantitative Measurement Data
A quantitative measurement and processing method technology, applied in the field of metrology processing of qualitative and quantitative measurement data, can solve the problem that quantitative measurement cannot be guaranteed, the accuracy and reliability of qualitative measurement results cannot be evaluated, and the biological measurement activities are affected. and other problems, to achieve the same mathematical meaning and ensure the effect of scientificity

Embodiment 1
[0087] Embodiment 1——quantitative measurement
[0088] (1) For the fatty acid binding protein FABP, the sample was measured 10 times by isotope dilution mass spectrometry, and the results were 50, 51, 52, 50, 51, 53, 50, 52, 54, and 52 ng / μL. Expressed in a way, the measurement result set X can be expressed as:
[0089] X = {50, 51, 52, 53, 54}
[0090] Since the elements in the set are required to be different in mathematics, the value with the same measurement result is reflected as an element in the set. Clearly, a single measurement of x i are consistent with the following relationship:
[0091] x i ∈X
[0092] (2) Determination of the confidence range of FABP quantitative results. For the 10 quantitative measurement results of FABP: 50, 51, 52, 50, 51, 53, 50, 52, 54, 52ng / μL, the expanded uncertainty corresponding to the 95% confidence probability was evaluated according to the GUM guidelines. The average value of 10 measurement results is 51.5ng / μL, and the expan...
Embodiment 2
[0101] Example 2 - Qualitative Measurements
[0102] (1) Perform a qualitative test on a sample that may be mixed with genetically modified ingredients. According to the national testing standards for genetically modified ingredients, if the genetically modified ingredients are detected, report positive; if no genetically modified ingredients are detected, report negative. For this sample, the test is repeated 100 times, including 2 negative test results and 98 positive test results, which are expressed in a set way, then the measurement result set X can be expressed as:
[0103] X = {negative, positive}
[0104] Since the elements in the set are required to be different in mathematics, the value with the same measurement result is reflected as an element in the set. Clearly, a single measurement of x i are consistent with the following relationship:
[0105] x i ∈X
[0106] (2) Determination of the confidence range of the qualitative measurement results of the transgene....
Embodiment 3
[0113] Example 3 - Qualitative Measurements
[0114] (1) Use a urine analyzer to test the urine of a certain patient, and repeat the test 100 times for this sample, including 2 times when the test result of urine protein is "-", and 6 times when the test result is "±" , the detection result is "+" 92 times, which is represented by a set, then the measurement result set X can be expressed as:
[0115] X = {-, ±, +}
[0116] Since the elements in the set are required to be different in mathematics, the value with the same measurement result is reflected as an element in the set. Clearly, a single measurement of x i are consistent with the following relationship:
[0117] x i ∈X
[0118] (2) Determination of the confidence range of the qualitative measurement results of the urine test results. Qualitative measurement results for 100 urine samples: 2 times of "-", 6 times of "±", 92 times of "+", calculate the frequency of each element in the measurement result set, obviousl...
