| Bone marrow smear interpretation A laboratory review of a bone marrow sample slide to examine cell structure and identify abnormalities. |
86 | $50 | $196 |
| Flow cytometry DNA or cell analysis, first marker A laboratory test that uses a laser to analyze cells or DNA by detecting a specific marker on the cell surface or within the cell. |
81 | $54 | $192 |
| Body fluid smear cell examination A laboratory test where a sample of body fluid is spread on a slide and examined under a microscope to check for abnormal cells. |
67 | $52 | $189 |
| Manual microscopic genetic analysis of tissue A laboratory test that manually examines tissue samples under a microscope to analyze genetic material. This initial procedure involves direct visual inspection to identify specific genetic characteristics. |
55 | $75 | $279 |
| Tissue culture for bone marrow and blood cell tumor disorders A laboratory test that grows bone marrow or blood cells in a culture to analyze tumor disorders. |
52 | $141 | $431 |
