Biomarkers for lymphoma
A biomarker, method, test kit, and diagnostic system for detecting the presence of lymphoma in a person are disclosed. The lymphoma may be Hodgkin's lymphoma or non-Hodgkin's lymphoma. The person may be a high-risk subject. In one embodiment, a plasma sample from a person is obtained. The level of at least one protein listed in Table S3 in the plasma sample is measured. The level of at least one protein in the plasma sample is compared with the level in a normal or healthy subject. The lymphoma is diagnosed based upon the level of the at least one protein in the plasma sample in comparison to the normal or healthy level.
1. A method consisting of:
measuring the level of all proteins listed in Table S3 in a plasma sample from a person; and
comparing the level of the proteins in the plasma sample with the level of the proteins in a normal or healthy subject.
2. The method of claim 1 , wherein the person has lymphoma.
3. The method of claim 1 , wherein the person has Hodgkin's lymphoma or non-Hodgkin's lymphoma.
4. The method of claim 1 , wherein the measuring comprises contacting the plasma sample with a reagent that reacts with proteins in the plasma sample to detect the presence of the proteins listed in Table S3.
5. The method of claim 4 , wherein the reagent is an antibody.
6. The method of claim 3 , wherein the person is infected with human immunodeficiency virus (HIV).
7. The method of claim 1 , wherein measuring the level of all proteins listed in Table S3 comprises analyzing the plasma sample with mass spectrometry.
8. The method of claim 1 , wherein comparing the level of the proteins in the plasma sample to the normal or healthy subject comprises determining if the level of all of the proteins listed in Table S3 in the plasma sample differ by at least 1.5 fold in comparison to the level of all of the proteins listed in Table S3 in the normal or healthy subject.
