There are so many politics and regulations in healthcare - not to mention the corruption (with barrier to entry) that tends to ride along with it.
I think PCT will find solid and profitable footing soon in healthcare - this industry tends to take a lot of time to break in to. Once the red tape is cleared and product placement occurs, revenue begin to flows in. Keep in mind that many of these hospitals may be on a Net 90 type payment agreement, so this revenue may show more in following quarters.
However, it will/should be higher $$$ (as fluids must be used and not crystals) and very consistent.
