I work in a hospital and lab and most of these test are sent out to a reference lab and can up to 7 days for final reports to come back and get to your Dr. The cell count and glucose are done in the hospital lab. Cytology is sent to the pathologist at the hospital. Your Spinal fluid will arrive at the lab with the order, the lab will pour off the correct amount of MLs into sterile containers using sterile pippetts. The specimens wll be picked up by the refence lab by the end of the day. The next day the reference lab will set up the test and start the process. Most times the hospital get the final reports within several days but then they need to go to the Dr. I had to wait 2 weeks for mine.
Good luck today, I know you will be fine just relax, take deep calming breaths. It didn't hurt me and I did not get a headache so I'm sure you'll do fine. I know how hard it is to wait. I hope this helped explain why it takes as long as it does. If you need more info let me know and I'll try to anser your questions in more detail. Hang in there sweetie.
