The invention relates to the technical field of medical diagnostics.
Thyroid tumors can be divided into two types including benign tumors and cancers. The property of a
thyroid nodule is difficult to determine clinically; and even if
biopsy is carried out, the benign tumors and the cancers are not easy to clearly identify due to
thyroid adenomas and focal nodular
hyperplasia. The invention provides a blood micro-molecular metabolin specific chromatogram which is used for identifying papillary
thyroid carcinomas, benign
thyroid tumors and blood of
normal people, and a manufacturing method of the blood micro-molecular metabolin specific chromatogram. A micro-molecular metabolin comprises two blood metabolin marks, namely palmityl
carnitine and
carnitine; the molecular weights of the palmityl
carnitine and the carnitine are 400.2634 and 161.20; and corresponding ions detected on a
mass spectrum are 404.5532 and 160.7866. A clinical experiment shows that the accuracy of applying a chromatogram formed by a specific value of the two
metabolism micro-molecules to judge the
thyroid cancer is 74% and the accuracy of judging non-
cancer (the benign thyroid tumor and the
normal people) is 72.3%. The blood micro-molecular metabolin specific chromatogram disclosed by the invention has the
advantage of high sensitivity and can be prepared into a diagnosis kit for screening and auxiliary diagnosis of the
thyroid cancer.
