Complete Blood Count (CBC) Checks for abnormalities in red and white blood cells, potentially indicating blood cancers.

Tumor Marker Tests Measure specific substances elevated in certain cancers, but not definitive alone. 

Circulating Tumor Cell (CTC) TestsDetect cancer cells shed from tumors into the bloodstream, promising for early detection 

Multi-Analyte Profiling (MAP) TestsAnalyze multiple blood components to identify patterns suggestive of cancer, still under development. 

Liquid biopsyAnalyzes cell-free DNA circulating in blood, potentially containing tumor DNA fragments. 

DNA methylation analysisDetects abnormal patterns of methyl groups attached to DNA, potentially indicating cancer. 

MicroRNA profilingMeasures levels of microRNAs, tiny molecules involved in gene regulation, which can be altered in cancer.

Exosome analysisExamines exosomes, tiny vesicles released by cells, which can carry cancer-associated molecules.

Protein profilingMeasures the levels and modifications of various proteins in blood, some of which may be associated with cancer. 

Autoantibody testingDetects the presence of autoantibodies, immune system proteins that mistakenly target the body's own tissues, which can be associated with certain cancers.
