Assessing vitamin D nutritional status: Is capillary blood adequate?
Our study demonstrates excellent agreement with no evidence of a clinically important bias between venous and capillary serum 25OHD concentrations measured by LC/MS-MS over a wide range of values. Under those conditions, capillary blood is therefore adequate for the measurement of 25OHD.
These results provide strong evidence that CXCL1 plays an important role in gastric cancer progression and migration and suggest that CXCL1 is a promising marker for the detection and prognosis of gastric cancer.
