... csf is formed by filtration and then secretion from networks of capillaries called choroid
plexuses which by the way is present in four cerebral ventricles. It produces 500 ml a day of csf which doesnt seem a lot but it manages to replace
the total volume of csf 2 or 3 times over in 24 hours. ... It has been shown that an increase of csf production occurs on night time hours almost
doubling production of the daytime hours.The functions of csf are very important. ... Csf is acquired by inserting a long needle into your back while you are sitting bent forward. ... As you can imagine this is a very painful procedure to go through so we should be very careful when
handling the csf specimens we receive.It is recommended that you at least collect 4 tubes with 2 ml of csf in them 1st tube should go to chemistry
, second tube should go to microbiology, third tube should go to hematology and the 4th tube should go to serology. ... Up to 20 ml of csf could be taken out in the spinal tap procedure. ... You should also examine the csf
specimen you receive.
