However, it can be difficult to obtain sufficient lung tumor tissue for testing. In such cases, a new blood test can be used instead, suggest the results from a "real world" study presented last week at the 2015 European Lung Cancer Conf...
the concordance between peripheral blood and tumor tissue samples in EGFR mutation detection remains variable. The question as to whether real-time samples for EGFR mutation analysis are required before epidermal

blood. METHODS: Plasma, serum and tumor tissue samples from 164 NSCLC patients were assessed for EGFR mutations using Amplification Refractory Mutation System (ARMS). RESULTS: Compared with matched tumor tissue, the concordance rate of EGFR mutation status in plasma and serum was 73.6% and 66.3%,...
A glomerular filtration rate (GFR) test evaluates kidney function. The kidney consists of tiny filters called glomeruli that remove waste material from the blood. This GFR test is an assessment of how well this filtration process is working. ...
A sample of cancer cells from a biopsy or surgical removal of cancerous tissue; a blood sample drawn from a vein (liquid biopsy) may be used in some situations. Test Preparation Needed? In many cases preparation is minimal, but it will depend upon how the cancer cells are being obtained....
In this group, which did test positive for T790M by tissue, the ORR was 64% and the median PFS was 15.2 months. “When we studied the tumor results on patients who were T790M-negative in the blood we could differentiate those who do better or worse on osimertinib, meaning that a biopsy...
Your healthcare provider may also be able to check for the mutations via a special blood test called a liquid biopsy, which analyzes DNA that has been shed from tumor cells in your blood.8Often, the DNA sample from a blood draw is not significant enough to make a clear diagnosis, but ...

My blood test from last week has come back as abnormal. I can see my eGFR level has gone from 56 to 43 and creatine from 106 to 132 umol/l within 6 months. I’m a bit worried as to why it has dropped like this. I’m early 40s. Since Jan I have really reduced alcohol to ...
