How do I know if spreadsheet cells are merged using google apps script

Question

In a Google docs spreadsheet. If cells A1 & A2 are merged, is there a way to confirm they are merged, using google apps script?

There is a merge function in GAS

But only works for active range

// This is my function to test the active range is merged or not and return
// true or false by passing active range to it
function ismerge() {
  var spread = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = spread.getActiveSheet();
  var last_row = sheet.getActiveRange().getLastRow();
  var last_col = sheet.getActiveRange().getLastColumn();

  Logger.log("Last row: %s", last_row);
  var active_row = sheet.getActiveRange().getRow();
  var active_col = sheet.getActiveRange().getColumn();
  Logger.log("Row: %s", active_row);
  if ( (last_row == active_row) && (last_col == active_col) ) {
    Logger.log("Cell not merged");
    return false;
  }
  else {
    Logger.log("Cell merged");
    return true;
  }
}
