You can try something like that, to find the top level category of your post. The post should be associated with category and subcategory, too.

//get all categories of current post
$categories = get_the_category($post->ID);

//get top level category of current post
$top_cat_obj = array();
foreach($categories as $cat) {

    if ($cat->parent == 0) {
        $top_cat_obj[] = $cat;  
    }

}           
$top_cat_name = $top_cat_obj[0]->name;
$top_cat_slug = $top_cat_obj[0]->slug;
