General | Latest Info

Stool sample is require. Samples may be collected in privacy of your home. Typically, you will be supplied with kit to collect entire bowel movement and send it to lab. Follow all instructions that are provided with kit to collect stool samples that are not contaminated with urine. Follow shipping instructions and timing because samples must arrive at testing laboratory within specified time frame. Stool DNA Test, Also Called Stool DNA-fecal Immunochemical Test, Is Combination Test That Detects Specific Changes In Several Genes Associated With Colon Cancer Within Cells Shed In Stool, As Well As Trace Amounts Of Blood In Stool. These genetic changes and small amounts of blood may be first and sometimes only signs precancerous growths or early colon cancer, making this stool-base Test useful screening tool. Detecting precancerous polyps and / or colon cancer early increases chances that they can be successfully treat. By combining two types of tests, stool DNA Test increases chance of detecting polyps and colon cancer. Stool DNA tests For: DNA changes associated with colon cancercancer Is caused by changes DNA inside our cells. These changes can cause cells to grow divide uncontrollably. Stool DNA Test Detects changes associated with colon Cancer in DNA of cells that shed from digestive tract into stool. Trace amounts of blood Although there are several possible causes of blood in stool, one important cause is presence of polyps or cancer in digestive tract. Colon polyps are common as people age, but most polyps do not cause any problems and are benign. However, benign polyps can turn into cancerous polyps and cancer may even spread to other parts of body. Polyps are finger-like growths that protrude into cavity of colon or rectum. They can be fragile bleed intermittently, such as when food waste brushes against them, leading to blood on stool. This test uses method called fecal immunochemical testing to detect trace amounts of blood on stool. Fecal immunochemical Test globin part of hemoglobin in red blood cells. Test Is Specifically Designed To Detect Globin From Human Blood And Not From Foods That You Eat. Therefore, dietary restrictions not necessary before testing. Also, hemoglobin from bleeding in upper digestive tract is break down before it reaches lower digestive tract and so upper GI bleeds are not usually detected by this test. American Cancer Society And US Multi-Society Task Force On Colorectal Cancer Recommend Testing Every 3 Years When You Choose Stool DNA Test As Method Of Screening For Colon Cancer. US Preventive Services Task Force Suggests Every 1 To 3 Years. This is because stool DNA Test still relatively new, and recommended screening frequency is still evolving.

Results of Threshold Analysis

In threshold analyses, two models find that reimbursement for mtSDNA test must be considerably lower, in range of $6-18 per test, for triennial mtSDNA Screening to be efficient and potentially cost-effective strategy. In one model, there was no level of reimbursement at which triennial mtSDNA testing would be cost effective compared with currently recommended screening options, due to being low relative to other tests. If triennial mtSDNA test strategy would motivate individuals who would not otherwise be screened to participate in screening, then threshold cost at which mtSDNA strategy would be on efficient frontier would increase. Adherence with mtSDNA testing would need to 31-53 percentage better than with other tests in order for triennial mtSDNA testing to be efficient at base-case reimbursement rate of $512. If mtSDNA assumed to perform better at detecting disease or if other modalities were assumed to perform worse than assumed in base-case Analysis, estimated reimbursement rates increase to $32–42 and $40, respectively. When interval of mtSDNA Screening was shortened to 2 years 1 year, threshold costs increased to $51 and $70, respectively. WTP Threshold Only Influences Threshold Cost Of MtSDNA Test When We Assume That Adherence With MtSDNA Testing Would Be Higher Than With Other Strategies. For SimCRC threshold cost is affected by WTP threshold at 17 percentage higher adherence, for MISCAN threshold cost is affected by 24 percentage higher adherence, and for CRC-SPIN threshold cost is affected by 36 percentage higher adherence.

METHODS

To compare simultaneous bacterial and fungal DNA extraction effectiveness, we use two types of fecal material, germ-free mice feces, for their absence of viable microbiota and very low background microbial DNA load originating from diet and bedding sterilized by irradiation, confirmed also in our and single human stool stock representing natural sample type control to ensure identical microbial composition in all samples. Germ-free feces were inoculated with known quantities of clinical bacterial and fungal to evaluate methods yields using real-time PCR. Strains were chosen as typical representatives Gram-positive, yeast and filamentous microorganisms, respectively. Human feces serving as vehicle were analyzed to compare DNA extraction methods in terms of integrity, purity, DNA quantity and microbial composition. Use Of Single Human Stool Sample Was Intended To Avoid Effect Of Inter-individual Variability Observed Elsewhere. Detailed Study Design Is Shown In Figure 1.
