Fecal DNA and RNA Collection: Uncovering Information from Stool Samples

Fecal samples contain hundreds of thousands of microbes that may unlock information on what is happening inside our bodies. These various types of bacteria are unique to everyone and were shown to correlate with disorders such as gastrointestinal infections, malabsorption syndromes, and inflammatory bowel diseases.

Many stool samples are generally collected by placing a clean piece of paper or plastic wrap over the rim of the toilet, defecating, then scooping the feces with a spoon, from the toilet into the sample container and sealed. The paper or plastic wrap and spoon will have to be disposed of. The sample will need to immediately be dropped off at a lab or placed in a plastic bag and refrigerated in the patients home. This process is messy, time restrictive, and often results in low patient compliance for providing stool samples.

The iSWAB™-Microbiome remove the inconvenience from stool sample collection. The Mawi fecal kit includes a flushable FecesCatcher that captures the stool after defecating and a swab to probe the fecesAfter collection, the swab is inserted into the iSWAB™ device. Once the sample is collected in the tube, the swab is removed and tossed. The iSWAB™ device is then sealed and can be sent to a lab for further analysis. The sample can remain at room temperature for several weeks until processed by the lab.

In the lab, a mixture of methods will be used to extract and analyze the DNA and RNA from the stool so that it can be analyzed. This includes qPCR, and sequencing.The lab results will then be able to determine the microbial community that is present inside the human host and provide information related to gut or other health issues .

Bacteria can grow uncontrollably within the collected sample without proper ways of transportation or storage thus not giving the lab an accurate depiction of what is happening inside our bodies. Mawi DNA recommends the use of a stabilizing sample device like the iSWAB-Microbiome. The stool sample will remain stable due to the stabilizing agents within the device. This guarantees that the stool sample the lab receives will be the closest representation of what was active in the gut.

Forensic DNA Collection: Techniques Used in Crime Scene Investigations

Forensic DNA collection is usually performed in crime scene investigations. This could be swabbing for touch DNA, extracting DNA from bloodstains, bodily fluids, and saliva. In many crime scenes, DNA crime scene samples may be the only clue left.

Mawi DNA created the innovative iSWAB™-ID, a processing tool that can collect DNA from anything that can be swabbed. It is sensitive enough to capture Touch DNA which allows for a double identification: the fingerprint, and the DNA present on the fingerprint.

Forensic DNA collection is hugely important to criminal investigations as it can help law enforcement officers ID both victims and perpetrators of a crime. It is also important for maintaining a chain of custody between lab workers and law enforcement officers.

The ability to collect DNA from crime scenes has only been a recent discovery and wasn’t standard practice until the late 80s. The use of DNA samples in a crime scene has been a large breakthrough in the forensic community, because it offers scientific proof.

DNA Collection for Genetic Testing: Ensuring Accurate and Reliable Results

Proper DNA collection techniques are crucial for accurate, reliable, and ethical genetic testing.

When collecting data, you face many issues that can stand in the way of procuring high-quality DNA samples. Cross-contamination, low ratio of DNA from targeted host, DNA degradation- are all issues that can interfere with DNA analysis Following the best practices for collection combined with innovative cell collection technology can help ensure these issues are mitigated.

More accurate and valid genetic test results contribute to better patient care, diagnosis, treatment, and counseling, so it’s worth taking steps to ensure this.

Ethical Considerations: Privacy and Consent in DNA Collection

While it isn’t relevant to the actual process and techniques of collecting DNA, it’s important to note that there are some ethical considerations. Namely privacy and informed consent.

The individual whose DNA is being collected must be informed about it and allowed to provide consent.

What’s more, their privacy should be maintained, which means only taking data about the person (their name, date of birth, sex, address, etc.) that is necessary to inform them of their results.

DNA Sampling Methods Depend On the Situation

There are many methods of DNA collection: saliva, buccal cells, hair, skin, blood, etc., and the person you are collecting samples from can determine which method to use. For most adults, the ability to collect saliva samples may be adequate, but for the elderly and infant population, it may be difficult to provide the volume of saliva needed. Ultimately, collecting buccal sample is the most universal way to gather a DNA sample. This is because only a quick swab of the inside of the person’s cheek is sufficient in providing an adequate sample.

Understanding this issue is what drives Mawi DNA to design sample collection devices that are accessible to everyone. The iSWAB technology is a universal collection option for those who want to ensure their DNA sample is collected properly the first time.
