Do You Have Malignancy?

The biggest thing in this patient is to decide is it a transit date or an exit date and do I think that the space is infected? This is where we get into lights criteria, which I feel like is the bane of medical students everywhere because the numbers are so close. So there are three main ones. Number one, plural protein over serum protein is greater than 5.5. Number two, plural LDH over serum LDH is greater than.6. And number three, pluralLDH greater than two thirds, the upper limit of normal. If you have anyone of these positive, then you most likely have an exit date.
