HOME PAGE The Home page is where you begin your queries. The design of PathIQ ImmunoQuery helps pathologists: find antibodies that identify a diagnosis find diagnoses that match staining results analyze results of previous immunohistochemical investigations learn about diagnoses and antibodies by accessing the database information. In the left column are the three main search function tabs: Build Dx Panel Build Ab Panel Analyze Results PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 6
In the center column are the sections for: saved results of previous database queries that you can easily link to for analyzing your results when the staining is done Learn About text fields for retrieving information about diagnoses and antibodies included in the system SMART SEARCH To start a smart search: 1. Select the Build DX Panel, Build AB Panel or Analyze Results tab. 2. Enter a full or partial diagnosis keyword or antibody name into the relevant search box. 3. Try entering only three letters if you are unsure of the spelling or correct name. In this example, we are searching for a diagnosis that contains the letters adeno. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 7
Click View All to see all diagnoses or antibodies in ImmunoQuery. Click the green plus sign to add a correct name to the relevant query Selected box. Click the red minus sign to remove a name from the Selected box. Mouse over the blue information icon to display associated discrete diagnosis names or clone names. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 8
BUILDING A DIAGNOSIS PANEL Single Diagnosis Panel A single diagnosis panel lets you see the success of antibodies in identifying a diagnosis, as reported in the current literature. To run a single Diagnosis panel: 1. Type in a diagnosis name in the search box to display corresponding matches (in this example, Adenocarcinoma, NOS). 2. Click on either the green plus sign or the diagnosis name to select a diagnosis. 3. You can modify the search sensitivity or minimum reference settings by clicking the radio buttons below the Selected Dxs box (or on the next screen). 4. Click the Build Panel button. The single diagnosis panel displays a comprehensive list of: antibodies (sorted by percent positive) the number of cases included in the references the confidence interval (CI) range the number of references. From this panel you can: display bibliographic information of associated references by clicking the # of Refs hyperlink. open an associated Learn About page by clicking on either the diagnostic group name or antibody name modify the search sensitivity or minimum reference settings by clicking the radio buttons above the right column PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 9
sort results alphabetically by clicking the Antibody hyperlink at the top of the column. sort results by percent positivity by clicking on the Positive hyperlink at the top of the column. (By default, the display shows search results sorted by decreasing percent positive.) rebuild the panel by setting the sensitivity or minimum number of references. Click the Return button to return to the home page. Multiple Diagnoses Panel A multiple diagnoses panel helps you determine which antibodies to use to distinguish between diagnoses. You can select up to three diagnoses for comparison. 1. Begin typing a diagnosis (for example, mesothelioma) in the diagnosis smart search field. 2. Scroll down until you find the diagnosis group name Mesothelia, All. 3. Click the diagnosis name to have it added under Selected Dxs. 4. Go through the same steps with adenoca. (The NOS diagnosis group includes the broadest range of antibodies for adenocarcinoma and helps distinguish most adenocarcinomas from mesothelioma.) 5. Use the Set Sensitivity radio buttons to define how sensitive the staining search criteria should be, on a scale of 1 to 3. 6. Use the Set Minimum Refs radio buttons to specify the number of references you want included in the analysis. 7. When you have selected the diagnosis groups, sensitivity, and minimum references, click the Build Panel button to bring up the expanded Comprehensive Panel and the collapsed Suggested Panels. You expand or collapse each panel by clicking the plus and minus signs. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 10
Set Sensitivity The Set Sensitivity radio buttons let you define how sensitive the staining search criteria should be, on a scale of 1 to 3. The buttons work as shown: Set Minimum Refs The Set Minimum Refs radio buttons let you specify the number of references you want included in the analysis. Some antibodies are associated with a particular diagnosis in only one reference, while others have many associated references. Increasing the number of minimum references narrows the list of antibodies, but increases the confidence for your search. Changing the minimum references includes or excludes suggested antibodies based on the number of references. Using the default setting of >1 provides moderate confidence. If you build a Dx panel and see no antibody results, check to see which Set Minimum Refs radio button is clicked. If only one reference includes the diagnosis you are researching, then the default setting of >1 will not be helpful and you should click the All radio button PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 11
Comprehensive Panel The Comprehensive Panel is an inclusive list of antibodies that may be useful in differentiating the diagnoses you selected in this example Mesothelioma, All and Adenocarcinoma, NOS. By default, the Build Panel results display as a collapsed Suggested Panel and an expanded Comprehensive Panel. Clicking the plus or minus sign next to each panel will expand or collapse the associated panel. The selected diagnosis groups are in the columns and the antibodies are in the rows. The display shows: the % positive for each antibody the number of cases included in references the images associated with that antibody a visual marker that helps you discern whether the antibody differentiates one diagnosis group from the other. From this panel you can: Click any antibody name to learn about the antibody. Click a diagnosis name to learn about the diagnosis. Mouse over the blue information icon to display associated discrete diagnosis names or clone names. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 12
Click on the View References hyperlink to access the references used for data on the antibody. The hyperlink shows up to the right of an antibody as you mouse over its name. Use your Internet browser s print command to print the Comprehensive Panel search results. Save the panel for future analysis by clicking Suggested Panel Applying further analysis to the data shown in the Comprehensive Panel, ImmunoQuery produces a brief Suggested Panel listing the antibodies most likely to provide the strongest differentiation between the diagnosis groups. The Suggested Panel displays: diagnosis groups in columns antibodies in rows color-coded reactivity icons that show an antibody s reactivity, located at each diagnosis group-antibody intersection In this example, MOC-31 and CK5 are the best differentiators for these diagnoses. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 13
From this panel you can: Click Exclude this Antibody if you don t want to include the antibody in the analysis. For example, if you exclude MOC-31, ImmunoQuery recalibrates and provides another best differentiating antibody, in this example MUC4. Add an antibody by mousing down the list of antibodies on the Comprehensive Panel and clicking where this icon appears. You might want to do this for an antibody that you use in your lab. Set the staining sensitivity or minimum references to different values to recalculate the Suggested Panel. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 14
Click on View References for any antibody to see which references support the selected antibody. Click the associated article s reference hyperlink to access its PubMed information. Click on the antibody name to learn about the antibody. Click on the diagnosis name to learn about the diagnosis. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 15
Click on Panel History to track changes made to the Suggested panels and restore the panel to its initial state. Click the Ask An Expert box to get additional information on your query. ASK AN EXPERT Amirsys asked 13 acclaimed experts in their respective fields to suggest which antibodies they would use to confirm a diagnosis. The result is the Ask An Expert feature. These customized panels offer at least 500 distinct two diagnoses and three diagnoses queries. Compare our meta-analysis with what a world-renowned expert suggests and improve patient care through increased diagnostic effectiveness. To access an expert panel, click the Ask An Expert check box in both a one diagnosis and 2+ diagnoses searches. In general, a combination of empirical and evidentiary information weighs in when determining which antibodies will be used to diagnosis a specimen. The Ask An Expert feature provides the pathologist with the first and only source for simultaneously viewing empirical and evidentiary support. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 16
Plus (+) and minus (-) signs signify the reactivity that the expert attributes to a particular antibody and diagnosis combination. This information is juxtaposed with data from the meta-analysis for comparative purposes. To return to the Comprehensive Panel, click Ask An Expert again to remove the check mark. SAVE CASE After you ve built a panel, you can save it. If you built only a Comprehensive Panel, you can save it to view later, for example if you haven t the time immediately to finish studying it. If you have also opened a Suggested Panel, you can save it to view later or until any immunohistochemical tests you ordered are ready for analysis. You can save a suggested panel containing up to five antibodies for further analysis. If you don t want to save a panel, click the Return button to go back to the Home screen. 1. Save your panel by clicking the Save Panel for Analysis button. 2. Complete the Save Case popup by entering a HIPPA-compliant description. PathIQ ImmunoQuery User s Guide 2.8 v.2 2010 17
