Your Guide to Swabbing for Family Tree Dna
Taking your DNA sample with Family Tree DNA is a straightforward process designed for ease and accuracy. The kit you receive contains everything you need, and following these instructions carefully will ensure your sample is viable for analysis. The key is to collect enough cellular material from the inside of your cheeks. These cells contain the DNA that scientists will analyze.
What’s Inside Your Family Tree Dna Kit?
Before you begin, it’s helpful to know what to expect in your kit. Typically, you’ll find:
- Two DNA collection swabs: These are specialized swabs designed to collect cheek cells.
- A saliva collection tube (for some tests): While cheek swabbing is most common, some tests might involve saliva. Always refer to the specific instructions included with your kit.
- A return mailer: Pre-addressed and often postage-paid for easy return to the lab.
- Instructions: A detailed guide specific to your test.
Preparing for the Swab
Proper preparation is crucial for a successful DNA collection. The goal is to avoid contaminating your sample or reducing the amount of DNA you can collect. Here’s how to prepare:
Timing Is Key: What to Avoid Before Swabbing
To ensure the highest quality DNA sample, it’s important to avoid certain activities for at least one hour before you plan to swab. This prevents food particles, beverages, or oral hygiene products from interfering with the cellular collection.
- Eating: Do not eat any food.
- Drinking: Avoid drinking anything other than plain water. This includes coffee, tea, juice, soda, and even milk.
- Chewing Gum: Refrain from chewing gum.
- Smoking: Do not smoke cigarettes or use any tobacco products.
- Brushing Teeth: Avoid brushing your teeth, as this can remove cells.
- Using Mouthwash: Do not use mouthwash.
If you absolutely must consume something or perform an oral hygiene task, rinse your mouth thoroughly with plain water and wait at least 15-30 minutes afterward. Plain water is the only exception to the drinking rule, and even then, a brief rinse is sufficient. (See Also: How to Kill Tree Borers: Your Expert Guide)
Finding a Clean Space
Choose a clean, well-lit area where you can sit comfortably without interruption. This will help you focus on the task and prevent accidental contamination.
Step-by-Step Swabbing Instructions
Now that you’re prepared, let’s get to the actual swabbing. Family Tree DNA provides two swabs to ensure you collect enough material. You will use both swabs for the collection process.
Step 1: Open the Swab Package
Carefully open the sterile packaging for one of the DNA collection swabs. Try not to touch the soft, cotton tip of the swab, as this is where your DNA will be collected. Hold the swab by the plastic handle.
Step 2: Begin Swabbing the Inner Cheek
Insert the swab into your mouth and gently rub the soft tip against the inside of your cheek. You’ll want to focus on the area between your gums and your cheek. Apply gentle pressure and rotate the swab. You should feel the swab collecting cells.
Technique Tips:
- Duration: Swab each cheek for approximately 30-60 seconds.
- Coverage: Ensure you cover a good surface area inside your cheek. Move the swab up, down, and in a circular motion.
- Pressure: The pressure should be firm enough to collect cells but not so hard that it causes discomfort or bleeding.
Step 3: Repeat on the Other Cheek
Once you have swabbed one cheek thoroughly, remove the swab from your mouth. Open the packaging for the second DNA collection swab. Repeat the swabbing process on the inside of your other cheek for another 30-60 seconds, using the same gentle but firm technique.
Step 4: Place Swabs Into the Collection Tube/bag
After you have swabbed both cheeks with the two separate swabs, it’s time to place them in their designated container. Your kit may come with a specific collection tube or a sealed bag for the swabs. Carefully place both swabs into this container. (See Also: How to Grow a Kiwi Tree From Seed: A Comprehensive Guide)
Important: Do not let the tips of the swabs touch anything else after swabbing, especially your fingers or any surfaces, to maintain sample integrity.
Step 5: Seal the Container
Securely close or seal the collection tube or bag containing the swabs. Ensure it is properly sealed to prevent any leakage during transit.
Step 6: Label Your Sample
This is a critical step. Your kit will include labels. Fill out all the required information accurately on the label, which typically includes your name, date of birth, and the date of collection. Attach the label firmly to the collection container.
Step 7: Prepare for Return Shipping
Place the sealed and labeled collection container into the provided return mailer. If your kit includes any other forms or documentation, ensure they are also included in the mailer as per the instructions.
Step 8: Mail Your Sample
Seal the return mailer and drop it off at the designated shipping location. Family Tree DNA usually provides a prepaid shipping label for convenience.
What Happens After You Swab?
Once your sample is mailed, it will be sent to the Family Tree DNA laboratory for processing. The lab technicians will extract the DNA from the cells collected on the swabs. This DNA is then analyzed to generate your genetic reports. The time it takes to receive your results can vary depending on the type of test you ordered and the current lab volume, but Family Tree DNA typically provides an estimated timeframe.
Tips for a Successful Sample Collection
To maximize your chances of a successful and accurate DNA analysis, keep these additional tips in mind: (See Also: How to Identify a Hazel Tree: A Comprehensive Guide)
- Be Patient: Don’t rush the process. Take your time to ensure you’ve collected a good sample.
- Gentle Pressure: Remember, you’re collecting cells, not scraping your cheek. Gentle pressure is key.
- Avoid Contamination: Wash your hands before you start and avoid touching the swab tips.
- Follow Instructions: Always refer to the specific instructions included with your Family Tree DNA kit, as there might be minor variations.
- Don’t Re-swab: If you think you didn’t get enough on the first try, don’t try to re-swab with the same swab. Use the second swab as intended.
- Storage if Needed: If you cannot mail your sample immediately, store the sealed collection tube in a cool, dry place. Avoid extreme temperatures or humidity.
Understanding the Different Test Types and Swabbing
Family Tree DNA offers several types of DNA tests, including the autosomal Ancestral Origins test, the Y-DNA test (for males), and the mtDNA test. While the fundamental swabbing technique is the same for all, it’s important to understand who each test is for:
- Autosomal Ancestral Origins Test: This test analyzes DNA from all your chromosomes and is suitable for both males and females. It provides insights into your ethnic breakdown and can help you find relatives across all branches of your family tree. The swabbing process is identical for men and women.
- Y-DNA Test: This test is exclusively for males. It traces your direct paternal line (father, father’s father, etc.). Only males possess the Y chromosome, so only biological males can take this test. The swabbing procedure is the same as for the autosomal test.
- mtDNA Test: This test traces your direct maternal line (mother, mother’s mother, etc.). Both males and females inherit mitochondrial DNA (mtDNA) from their mothers. The swabbing process is the same for both genders.
Regardless of the test you choose, the method of collecting your DNA via cheek swabbing remains consistent. The key is to ensure a sufficient amount of cellular material is collected from the inside of your mouth.
Troubleshooting Common Swabbing Issues
While the process is generally foolproof, occasional issues might arise. Here’s how to address them:
- Bleeding Gums: If your gums bleed slightly during swabbing, it’s usually not a problem. The lab can generally process samples with minor blood contamination. However, try to be as gentle as possible to avoid this. If significant bleeding occurs, rinse your mouth with plain water and wait 30 minutes before attempting to swab again, or use the second swab.
- Not Enough Cells: If you are concerned you haven’t collected enough cells, ensure you have followed the preparation guidelines strictly (no eating, drinking, etc. for an hour prior). Swab each cheek for the full recommended time (30-60 seconds) and apply gentle but firm pressure. Using both swabs as directed is crucial.
- Swab Tip Damaged: If you accidentally touch the tip of the swab to your finger or another surface before it’s in the collection tube, use the second swab. If both swabs’ tips are compromised, contact Family Tree DNA customer support for a replacement kit.
The Importance of Accurate Data Entry
Beyond the physical act of swabbing, accurately identifying your sample is paramount. Double-check that you have correctly filled out the labels with your name, date of birth, and the date you collected the sample. This information is linked to your account and ensures your results are attributed to you correctly. Errors here can cause delays or mix-ups.
What Not to Do with Your Swabs
To reiterate, avoid any actions that could compromise your sample:
- Do not eat, drink (other than water), smoke, or chew gum for one hour prior to swabbing.
- Do not touch the tip of the swab with your fingers or any other surface after collecting your sample.
- Do not place the swabs in a location where they could be contaminated by other substances.
- Do not attempt to re-use a swab.
By adhering to these guidelines, you are setting the stage for a successful genetic testing experience with Family Tree DNA. The simple act of careful swabbing is the first, vital step in unlocking the stories held within your DNA.
Conclusion
Successfully swabbing for your Family Tree DNA test is an accessible process that requires careful preparation and execution. By avoiding food, drink, and other oral contaminants for an hour beforehand, and by gently but thoroughly swabbing the inside of your cheeks with the provided sterile swabs, you ensure a high-quality sample. Following the step-by-step instructions for collection, sealing, labeling, and mailing is crucial for accurate results. This simple yet vital step is your gateway to exploring your ancestral origins and connecting with your heritage.
