| PBMC | When conducting blood sample analysis, we focus on separating and evaluating in detail the composition and counting of peripheral blood mononuclear cell (PBMC). This process involves identifying and quantifying various types of mononuclear cells in the sample, such as lymphocytes, monocytes, etc. These cells are crucial for understanding an individual's immune status. Through precise separation techniques and advanced cell analysis methods, we are able to obtain accurate and detailed reports on the classification and quantity of mononuclear cells. | About two and a half years |
