LAB 6 WRITE-UP

Bayesian Statistics

Overview of the Original Diagnosis System
Each group in the BME 100 class was given two patients and were instructed to test the patients for the disease-associated SNP. The total laboratory consisted of 34 teams total comprised of 6 students, each team was assigned two patients. In total there were 68 patients being tested for the disease. Originally, while testing the droplets of DNA with the fluorimeter, each testing sample had three pictures taken under the light of the fluorimeter. These images were then grouped, analyzed, and the data was then average, in hopes to find the most accurate data for each specific sample. Each patient had a three replicants of their DNA tested for the disease, this datas mean was then taken, therefore continuously potentially limiting error. The BME 100 class data was comprised in a master spreadsheet that included all of the teams work. Some groups data had successfully concluded their sample data, while others received inconclusive results, or left their information blank. Possible sources of error arise from the multitude of teams in the BME 100 class, because there were 34 teams, there were 34 different ways on doing the lab, therefore the data would not have been received in the exact same manner every time.

Computer-Aided Design

TinkerCAD

Using the TinkerCAD program, our group was able to refer to the standard open PCR machine we used earlier in this lab and in what ways it could be improved. With each improvement, we had to discuss the implications of the change, such as if the PCR machine was designed so it could hold more samples, the process would take longer, most likely need another heating and cooling element, and then causing a need for a larger powered circuit board. In conclusion, as a group we decided that we would add another cooling element to the existing PCR deign. This would not significantly change the design of the PCR machine but it would allow for the PCR reaction to be reached more efficiently and in less time.

Our Design

Description of image

 
We added a cooling element to the Open PCR machine. The process of PCR calls for a cooling stage, this added element allows for the test tube samples to reach the cool temperature more efficiently. Therefore, reducing the total time required for the PCR reaction.


Feature 2: Consumables Kit

We will hold the SYBR Green 1 in light blocking packaging which would replace the original tin foil used in the lab. The packaging would also be water proof to protect from cross contamination. The buffers needed to be sterile to ensure the cleanliness and accuracy of the lab. The packaging for the micropippeor tips could be cut in half that way they could all be used in one sitting for the lab and that would allow for the most sterile process.

Feature 3: Hardware - PCR Machine & Fluorimeter

For the fluorimeter we would include an adjustable camera holder that will allow for varying heights to have the camera flush with the side of the machine. We would also change the folding lid of the fluorimeter that way it allow for complete darkness, but still allow for a clear image. The lack of these two features in the existing fluorimeter design that we used caused some problems. Without the adjustable camera holder, each change in camera while testing to see who's worked better, the entire fluorimeter set up had to be redone. Also, lowering the flap with the camera on timer, caused glare and problems due to the camera adjusting to the light. In order to get a clear picture, the lab had to be slightly compromised and allowed to the flap to be open partially allowing some light to shine into the fluorimeter.
