The random Quality Control loading methods based on time series of enzyme linked immunosorbent detection
Technical field
The invention belongs to Bioexperiment equipment technical fields;It is related to the random matter based on time series of enzyme linked immunosorbent detection
Control loading methods.
Background technology
The used enzyme linked immunological of clinical detection antigen of hepatitis B virus antibody, c-hepatitis antibody, AIDS virus antibody at present
(ELISA) method carries out.Every batch of experiment has 80-100 test, and one weakly positive Quality Control of addition is needed to carry out the effective of monitoring test
Whether, weakly positive Quality Control detection proves that experiment is effective, does not detect, and proves to test that there are problems by the gross, is added in an experiment
Quality Control is all fixed position, and every batch of experiment has multiple hole positions, fixed Quality Control that can only be monitored to the fixed hole position tested by the gross,
All holes position that this batch experiment cannot be monitored whether there is problem, not be avoided that other holes position or experiment part due to being incubated temperature
Degree, the abnormal causes such as additional examination dosage lead to experiment, and there are problems, and then there may be the results of mistake.The present invention can be according to the time
Variation, generate different parameters, Quality Control position made to randomly generate, solving enzyme linked immune assay Quality Control can be to elisa plate
Each hole position is monitored, and can discover influence of the edge effect to testing result.
Random Quality Control at present can only be that quality-control product is manually randomly placed in the lot sample during every batch of is tested and is loaded
It is realized in this at random, every batch of experiment is required for manually mobile and specified Quality Control position, can be interfered by various factors.
The no good solution of randomization of ELISA Quality Controls at present, method are the processes in every batch of experiment sample-adding
Middle be randomly placed in quality-control product realizes that this mode makes sample-adding sample continuity be destroyed, sample at random in the lot sample sheet
By other detecting systems using when sample number may occur or information obscures mistake, quality-control product is placed may in sample sequence
It can pollute, influence the reliability of testing result;Certain position is specified to realize when sample-adding random, this mode can not rule out personnel
Influence factor, testing staff may even refer to without position according to personal custom, specified quality-control product fixed position relative
It is fixed, cause randomness poor, cannot find in time in detection process there may be the problem of, if disparity items be once loaded it is multiple
Quality-control product is also easy to make to obscure when testing staff designated position, and Quality Control is caused to be loaded mistake.

Specific implementation mode
Embodiment 1
The sample-adding that random Quality Control is carried out using 88 orifice plates is tested, and positive and negative control and quality-control product are loaded sequence frame and sample
It is loaded sequence rack position and each frame placement sample, Quality Control or control site is constant, according to time conditions during sample injector sample-adding
Variation, mathematical model is calculated and carries out sequence location and is replaced automatically, automatically will fixed position Quality Control inhale it is random after sample
To the holes elisa plate 1-88 any position, the sample application that picking is replaced by random Quality Control is ultimately formed to protoplasm control fixed position
Include the unfixed sample-adding combination of quality-control product and quality-control product position in 1-88 samples;The mathematical model is aRandom number*s。aRandom number
The arbitrary random number between 0-1, s are batch detection sample number (1-88);The HSL methods on the backstages automatic sample-adding system STAR-VENAS
Editing machine is based primarily upon C/C++ language;The last position for taking the current experiment time " dividing ", it is N1, the last position of second to switch to ASCII character postscript
It is N2 to switch to ASCII character postscript, and numerical value of N 3 is calculated using the formula of N1*10+N2;Repeat N3 calling random number generator
MthR01Draw () function, MthR01Draw () function are used to generate the random number between a 0-1, are denoted as aRandom number, use lot sample
This number (1-88) is multiplied by aRandom number, the non-integer between a 0-88 is obtained, five finally are given up using MthRound functions 4 to the number
Enter to obtain respective integer, the random Quality Control position using the integer as the batch sample, which is more than or equal to 0 and is less than etc.
In batch Sample Maximal number, if value taken is exactly 0 in extreme circumstances, then it represents that Quality Control position rests on foramen primum and do not hand over
It changes.
After sample-adding starts, the time of beginning is exemplified as sample injector:8 points 23 seconds 45 minutes, point last position be 5, the last position of second
It is 3, difference value, and it is converted into ASCII character, it is 0.86 to call the random number of random number (between 0-1) operation according to formula, from
Dynamic rounding is 0.9, is multiplied by sample total (batch maximum value is 88), if sample size is 88, then random Quality Control position is No. 72 positions.
By 73 days by a definite date, the random Quality Control sample-adding of 168 batches (88 sample of whole plate) was carried out altogether, each hole is added to quality-control product
Specific location and frequency see Fig. 1, Fig. 2.
The batch tested at present does not have enough, and there is also the Quality Control position not being fetched into, the frequency that individual holes take also is deposited
In higher situation, but according to mathematical model by taking 88 samples of whole plate as an example, using Microsoft EXCEL rand () letter
Number[3]Simulation 60000 times, the specific component of frequency that each hole is added to quality-control product is shown in Fig. 3.In the case where batch number is enough, 1-
87 each hole random frequencies are close, and the frequency that 0 hole (not making exchange hole) occurs with the 88th hole is the 50% of remaining hole.
