Sites: Investigation Levels Tab

Receptors must be assigned to the site (via the Receptors tab)

Investigation levels must be configured in the system (under Scientific Settings)

Rows - One row per receptor that has been assigned to the site (colour-coded to match the Receptors tab)

Columns - One column per analyte, grouped by concentration type

Cell values - The investigation level value for each receptor/analyte combination

Expand/Collapse All - Use the button to expand or collapse all sections (starts expanded by default)

Colour-coded rows - Each receptor row is colour-coded to match its colour indicator from the Receptors tab

Sticky row headers - Receptor names stay visible as you scroll horizontally through wide tables

Rotated column headers - Analyte names are rotated vertically to fit more columns on screen

Tooltips - Hover over values to see additional details

"NL" (Not Limiting) values indicate that a particular receptor/analyte combination does not have a limiting value

Edit Investigation Levels - Navigate to the Investigation Levels management page

Edit Guidelines - Navigate to the Guidelines management page

Edit Analytes - Navigate to the Analytes management page

Edit Receptors - Navigate to the Receptors management page

This tab is read-only — you cannot edit investigation level values directly from here

To change which receptors appear, go to the Receptors tab and update the selections

To change investigation level values, use the Investigation Levels page under Scientific Settings

Missing values (blank cells) indicate that no investigation level has been configured for that receptor/analyte combination

Use horizontal scrolling to navigate wide tables with many analyte columns

Use the quick links to jump directly to configuration pages if you need to update investigation level data

Review this tab after updating receptor selections to confirm the correct investigation levels are displayed
