| Procedure | Volume | Avg. paid | Avg. submitted |
|---|---|---|---|
| Flow cytometry, additional marker An additional marker is tested during a flow cytometry procedure to analyze DNA or cells. This step adds specific data points to the initial analysis. |
601 | $18 | $166 |
| Tissue pathology examination, moderate complexity A laboratory test where a pathologist examines tissue samples under a microscope to analyze cellular details. This intermediate complexity procedure involves specialized techniques to identify abnormalities in the tissue. |
483 | $46 | $277 |
| Infectious disease DNA/RNA test A laboratory test that uses a specific technique to detect the genetic material of an organism. This method amplifies the target DNA or RNA to identify the presence of the organism. |

140 | $34 | $86 |
| Flow cytometry, 16 or more markers A laboratory test that uses lasers to analyze cells or DNA using 16 or more different markers. This technique helps identify and characterize specific cell types based on their physical and chemical properties. |
92 | $63 | $259 |
| Nucleic acid test for multiple organisms A laboratory test that uses amplified probe techniques to detect the genetic material of multiple organisms in a sample. |
84 | $69 | $174 |
| Special tissue stain and interpretation A laboratory test using special stains to examine tissue samples, including the pathologist's review and written report of the findings. |
74 | $36 | $176 |
| Manual microscopic genetic analysis of tumor A laboratory test that uses a microscope to manually examine tumor tissue for genetic changes. |
68 | $50 | $320 |
| Blood smear interpretation with written report A physician examines a blood sample slide under a microscope to analyze blood cells. The doctor provides a written report of their findings. |
46 | $18 | $69 |
| Tissue preparation to remove calcium A laboratory procedure that removes calcium from a tissue sample to prepare it for microscopic examination. |
46 | $12 | $79 |
| Bone marrow smear interpretation A laboratory review of a bone marrow sample slide to examine cell structure and identify abnormalities. |
33 | $45 | $248 |
| VRE nucleic acid detection test A laboratory test that uses amplified probe techniques to detect vancomycin-resistant Enterococcus (VRE) DNA in a patient sample. |
28 | $34 | $86 |
| Staphylococcus aureus DNA test A laboratory test that uses DNA amplification to detect the presence of Staphylococcus aureus bacteria in a sample. |
28 | $34 | $86 |
| MRSA nucleic acid detection test A laboratory test that uses amplified probe techniques to detect the genetic material of methicillin-resistant Staphylococcus aureus (MRSA) bacteria. |
28 | $34 | $86 |
| Strep A nucleic acid amplification test A laboratory test that uses nucleic acid amplification to detect the presence of Group A Streptococcus bacteria. This method identifies the genetic material of the bacteria to determine if an infection is present. |
28 | $34 | $86 |
| Group B Strep DNA test A laboratory test that uses DNA amplification to detect the presence of Group B Streptococcus bacteria. |
28 | $34 | $86 |
| 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. |
27 | $54 | $201 |
| Pathology tissue examination, moderate complexity A laboratory test where a pathologist examines tissue samples under a microscope to identify abnormalities. This specific level indicates a moderate degree of complexity in the analysis. |
21 | $9 | $204 |
| Moderately high complexity pathology tissue examination A laboratory test where a pathologist examines tissue samples under a microscope to analyze cellular details. This specific level of complexity involves a moderate to high degree of technical skill and interpretation. |
19 | $62 | $604 |
