Use array names for input. I.E.:
<form action="" method="post" name="someform">
<input name="row[0][test_name]"/>
<input name="row[0][result]"/>
<input name="row[1][test_name]"/>
<input name="row[1][result]"/>
<input type="submit" name="submitted" value="send">
</form>
So upon submission, parsing in php, use filter_input with FILTER_REQUIRE_ARRAY as option:
<?php
$submitted = filter_input(INPUT_POST, 'submitted');
if(!empty($submitted)){
$rows = filter_input(INPUT_POST,'row', FILTER_DEFAULT, FILTER_REQUIRE_ARRAY);
$parsed_rows = [];
foreach($rows as $row){
if(!empty($row['test_name']) && !empty($row['result'])){
$parsed_rows[] = $row;
}
}
}
?>
