Biopsy: Removal of suspect tissue and examination by a pathologist is the only way to get a definitive answer. Cologuard facilitates selection of patients who should undergo colonoscopy. It does not diagnose colon cancer.

How much.: The recent assays pick up some anti-dna antibodies (double stranded) in many people without any disease. High titer dsdna antibodies are almost always sigificant! if you have them, why was the test ordered. And if truly positive, see a rheumatologist-and bring your labs!

Nucleotide sequence: Dna is a long chain of 4 molecules called nucleotides. The sequence of three in a row, codes for Amino Acids used to build enzymes and body parts. Other sequences turn the code on and off for certain segments. All of the codes are still not known and some information is transfered in other ways. All in all it is a remarkable bit of biology.
