36
what is collected in each tube for lumbar puncture?
Tube 1- cell count and differential
Tube 2- glucose and protein
Tube 3- culture andgram stain
tube 4- cell count and differental
**in tube 1 there should be a little blood from the puncture by the time you get to tube 4 there should be little blood**
37

Traumatic Puncture vs subarachnoid hemorrage
Traumatic Puncture
* CSF- low
* Duration of bleeding- decreases when CSF is withdrawn
* Clotting- present
* Repeat lumbar puncture- not blood
* centrifugation- clear fluid
Subarachnoid hemorrage
* CSF- high
* Duration of bleeding- no change in color when CSF is withdrawn
* Clotting- Absent
* Repeat lumbar puncture- bloody
* centrifugation- Xanthochromia

WBC in spetic willbe \> 80,000 and polys will be \> then 75%
