Check if a group's subfields have values

Is it possible to check if a fieldset's subfields have values? If none of the fieldset's fields have values it would return null.

$field = field_get_items('node', $node, 'group_name');
if ($field) {
   // At least 1 of it's sub-fields has a value!
   // None of it's subfields have values!
