I am not sure. The sitz marker test is a transit test to see how fast stool moves through the system.
sitz marker test
What is a sitz marker test?
A sitz marker test uses tiny 'markers' to test how fast food is moving through the intestines. It is most often used with patients who are suffering from chronic constipation, for example less than two bowel movements per week.
What happens during a sitz marker test?
Your doctor will give you a small capsule to swallow. This capsule contains small markers which will show up on x-rays and let the doctors track their progress through your intestines.
After several days you will asked to return to the doctor's surgery or hospital, and x-rays will be taken of your abdomen to see if any of the markers are left in your colon or whether they have all been expelled from the body. The more markers you have left in your body, the slower your colon motility.
don't read to much into this its just for the info, its important to ask your doctor when its all done what it all means.
"Colonic Transit Test
Colonic transit is often the first test performed when the goal is to distinguish slow-transit constipation from normal-transit constipation. It may also be used as a follow-up procedure for patients whose pelvic floor dysfunction has been corrected. Major advantages of this test include the fact that it is safe, simple, noninvasive, and cost-effective.
In this procedure, abdominal radiography is performed a specific number of days (eg, 5 days) after the patient swallows a capsule filled with radiopaque markers.[2,7] In normal controls, most markers are evacuated by day 5. In patients with slow colonic transit, however, more than 20% of markers remain in the colon, usually in an equally scattered pattern.[1,2,7] Retention of markers in a specific area (eg, the rectosigmoid region such as the lower left colon and rectum) with sufficient transit through the remainder of the colon may indicate mechanical obstruction.[1,2] The Sitz-Mark (Konsyl Pharmaceuticals; Forth Worth, Texas) test is the proprietary name of a commonly performed colonic transit test. More elaborate colonic transit procedures, involving ingestion of radiomarkers for several days and multiple radiographs, are warranted when additional information about regional colonic transit is desired. See Figure 6.
Sample Report: Colonic Transit Test
Normal Result: The patient ingested a Sitz-Marker capsule (with 24 markers) on October 24 (day 0). Twenty-four hours later (day 1), an abdominal flat plat found that all 24 markers were scattered throughout the colon, predominantly on the right side. An abdominal flat plate on day 3 found that 16 markers remained: 1 in the ascending colon, 3 in the transverse colon, 2 in the area of the splenic flexure, 5 in the descending colon, and 5 in the rectosigmoid area. An abdominal flat plate on day 5 showed no markers remaining.
Impression: Normal Sitz-Marker study.
Abnormal Result: The patient reported ingesting a Sitz-Marker capsule (with 24 markers) on October 17 (day 0). Twenty-four hours later (day 1), an abdominal flat plate revealed that all 24 markers were present, predominantly in the right colon. At 72 hours (day 3), an abdominal x-ray revealed that 24 of 24 markers were present: 12 were located in the ascending colon, 10 in the transverse colon, and 2 in the region of the splenic flexure. At 120 hours (day 5), 20 of 24 markers were still present, generally equally distributed throughout the colon: 6 markers were present in the ascending colon, 6 in the transverse colon, 6 in the descending colon, and 2 in the rectosigmoid area.
Impression: This pattern is consistent with colonic inertia.
