How To Do The Cologuard Test | Simple At-Home Steps

What The Cologuard Test Is And Who It Is For

The cologuard test is a stool based screening test for colorectal cancer that you do at home with a kit your clinician orders for you. It looks for hidden blood and DNA changes released by cells in the stool. That mix can point to polyps or cancer in the colon before symptoms show up.

Most average risk adults aged forty five and older can use this type of stool DNA test when their clinician feels it fits their screening plan. People with a strong family history of colorectal cancer or a prior diagnosis of colon cancer usually need colonoscopy instead.

Public health groups such as the Centers for Disease Control and Prevention and the American Cancer Society list stool DNA tests alongside colonoscopy and yearly stool blood tests as standard screening choices.

Preparing To Do The Cologuard Test At Home

A little planning makes the cologuard test much easier. Many people choose a morning when they usually have a bowel movement and can stay near home for an hour or two. Pick a day when you can drop the package at the shipping carrier before the last pickup so the sample does not sit through a long weekend.

When the box arrives, open it and check your name, date of birth, and the expiration date on the label. If anything looks wrong or the box is damaged, call the customer care number for help.

The kit includes written directions and illustrations. The official manufacturer site also hosts a clear step by step guide and video with the same steps you see in the printed instructions, which can help you feel familiar with the process before you start.

You do not need to avoid specific foods or stop most medicines for this at home stool DNA test, but always follow any directions your clinician gives you. Let your care team know about rectal bleeding, recent colon surgery, or long standing bowel diseases, since those can change which screening test fits your situation.

How To Set Up Your Cologuard Collection Kit

Before you sit down on the toilet, lay out all of the pieces on a clean surface near the bathroom. You should have a collection container with a blue lid, a bracket that attaches to the toilet bowl, a small sample tube with a built in scoop, a bottle of preservative liquid, a plastic bag with an absorbent pad, a molded tray, and the cardboard shipping box with a prepaid label.

Leave the plastic bag and tray in the bottom of the shipping box for now. Take the bracket and open the toilet seat. Place the bracket on the rim of the toilet bowl as shown in the pictures in your booklet. Seat the collection container into the circular opening so it hangs just below the seat. Make sure it feels steady and cannot tip when you sit down.

Next, twist off the blue lid from the collection container and save it on the flat surface. Check that the water level in the toilet bowl is low enough that it will not touch the bottom of the container. If needed, you can flush once before you place the bracket so you start with a lower water line.

Once everything is set up, wash your hands with soap and water. From this point, try not to touch the inside of the container or the inside surfaces of any lids, since that can introduce extra material the test does not need.

Step By Step: Doing The Cologuard Test At Home

Collecting The Stool Sample

When you are ready, sit on the toilet as you usually would. The goal is to pass stool directly into the open collection container. Try to relax and give yourself enough time rather than rushing. Some people find that placing their feet on a small footstool helps the bowel movement arrive more easily.

Do not let urine, toilet paper, or water from the bowl fall into the container. If you need to urinate, try to do that first with the container still closed, then set up the bracket and container after you finish. If urine or a large amount of water reaches the stool, contact the customer care line for advice, since the lab might not be able to process that sample.

Add Preservative And Seal The Container

After you pass stool into the container, stand up and carefully open the small bottle of liquid preservative. Pour all of it into the container. This liquid simply helps preserve DNA markers and blood signals in the stool while the kit travels to the lab.

Place the blue lid back on the container and twist it clockwise until it stops. Give it another gentle twist to confirm it is tight. Wipe any residue off the outside with toilet paper and flush that paper in the toilet. The container should stay upright in the bracket while you do this.

Fill The Sample Tube

Now pick up the small sample tube with the scoop built into its cap. Open it as shown in the picture in your booklet and use the scoop to take small portions of stool from different spots in the container. Scrape the scoop across the surface of the stool instead of digging deep. When the scoop is covered up to the fill mark, place it back into the tube and twist it closed until tight.

Shake the tube as the kit directions describe. This helps mix the stool with the liquid inside the tube so the lab receives an even sample to test. Then set the closed tube aside on the flat surface while you prepare the package.

What To Do With The Toilet And Remaining Waste

Once your sample and tube are closed, you can remove the bracket and collection container from the toilet. Use the disposable bracket as the instructions describe, usually by placing it in the trash. You will see a treatment packet or fluid in the toilet that helps break down remaining stool and protect plumbing. Follow the printed steps to add that material, wait the stated time, and then flush.

Wash your hands again with soap and warm water. Wipe down any surfaces that came in contact with the outside of the container or tube. The stool inside the sealed pieces will travel to the lab, while everything left in the toilet moves through ordinary plumbing once treated.

Packing And Shipping Your Cologuard Kit

The cologuard test depends on sending the kit back within the time window in the guide, usually within a few days. Many programs suggest collecting the sample early in the week so the lab receives it within about four days.

Place the closed collection container and the closed sample tube into the plastic bag with the absorbent pad, then seal the bag. Put the sealed bag into the molded tray, then place the tray into the original cardboard shipping box. Close the box, follow the flaps as shown in the diagram, and secure every tab.

Peel the backing from the prepaid shipping label and stick it to the area marked on the box. Many kits use national package carriers, and the directions list drop off spots you can use. Bring the box to the carrier the same day you pack it and ask the staff to scan the label so tracking starts right away.

Your clinician will usually receive your result within one to two weeks once the lab has the sample. Many programs also let you track your kit and see the result through a secure online portal, which can be helpful if you like to follow each step.

Topic	Practical Tip	Why It Helps
Timing The Test	Collect early in the week and mail the same day.	Reduces time in transit so markers stay stable.
Diet And Medicines	Follow your clinician advice and usual diet unless told otherwise.	Avoids confusion about changes that might affect bowel habits.
When To Wait	Hold off if you have diarrhea, heavy menstrual bleeding, or bright red rectal bleeding.	These can affect the sample and might point to issues that need direct care.
Label Checks	Match your name and date of birth on every piece.	Prevents sample mix ups at the lab.
Shipping Choice	Use the carrier listed, not a random drop box.	Some boxes sit longer, which shortens the viable window.
Travel Plans	Avoid collecting right before a trip.	You may not reach the carrier in time for pickup.
Staying Calm	Read the booklet slowly and watch the approved video once.	Most people find the process easier once they see it once.

Understanding Your Cologuard Test Results

The lab sends the cologuard test result to the clinician who ordered it. Reports usually list the result as negative or positive, along with a short explanation. A negative result means the test did not find stool DNA markers or blood above the cut off used for this kit.

A positive result means the lab found higher levels of one or more markers. It does not mean you have cancer for sure. Positive stool DNA tests can occur with advanced polyps, smaller polyps, inflammation, or sometimes with no clear growth seen later. Because of that, standard medical groups say that a positive stool DNA test should be followed by a colonoscopy to look directly at the lining of the colon.

Your clinician will discuss what the report means for you, taking your age, family history, and prior tests into account. Many programs follow a schedule where people with a negative stool DNA test repeat it about every three years, while those with a positive test move on to colonoscopy soon after.

Safety, Limits, And When To Call Your Clinician

Most people can use the cologuard test at home without problems. Still, there are limits. The kit is meant for people without symptoms who are at average risk. It is not built to monitor bleeding from hemorrhoids, long standing bowel disease, or prior colon cancer. It also does not replace colonoscopy for people with a strong family history of polyps or inherited cancer syndromes.

Call your clinician if you notice ongoing rectal bleeding, new belly pain, weight loss you did not plan, or bowel changes that last more than a few weeks. Also contact the customer care line or your clinician if you spill the preservative, drop the container, or miss the shipping window.

The printed patient guide in the kit reminds you not to drink the preservative liquid, not to open containers after sealing them, and to follow the listed steps exactly. Those guidelines protect both you and the staff who handle the package.

Frequently Asked Questions

How Long Does The Cologuard Test Take From Start To Finish?

The hands on part of the cologuard test usually takes about twenty to thirty minutes, including setup, the bowel movement, and packing the kit.

What If I Accidentally Get Urine Or Toilet Paper In The Container?

If a small drizzle of urine or a stray piece of paper reaches the sample, the lab may still be able to run the test. The booklet lists a phone number you can call to describe what happened in simple terms.

Can I Use The Cologuard Test If I Am On Blood Thinners?

Many people who take blood thinners can use stool based screening tests, but this choice always belongs to your clinician.

What Happens If My Cologuard Kit Expires Before I Use It?

Each box shows an expiration date that reflects how long the collection materials stay reliable. If that date passes before you collect your sample, call the customer care number or your clinician.

Does A Negative Cologuard Test Mean I Can Skip Colonoscopy Forever?

A negative stool DNA test lowers the chance of advanced disease for a period of time, yet it does not remove the lifetime risk of colorectal cancer.

Wrapping It Up – How To Do The Cologuard Test

The cologuard test offers a home based option for colorectal cancer screening that relies on stool DNA and blood markers rather than scopes or sedation. When used as directed, it can catch many cancers and advanced polyps.

The process comes down to a few main tasks. You review the booklet and video, set up the bracket and container, collect a stool sample without urine or water, add the preservative, fill the small tube, seal every piece, and mail the box the same day. Each step is simple on its own, and the kit supplies every part you need.

Screening choices always belong in a conversation with a trusted clinician who knows your history. If this type of test fits your situation, using the kit carefully at home can move colon screening from a future plan to a finished task on your list.
