what’s the solution used to dilute sperm for motility
PBS - Phosphate buffer solution
What does semen analysis includ
volume color viscosity liquefaction motility
what’s the reference range for motility for semen

when is motility of a semen sample read
within 1 hour of collection
Red cell diluent
saline
Diluent that destroys red cells and enhances wbcs
3% glacial acetic acid
for CSF analysis, what tubes are used to rule out bleeding
1 and 4
When do we count tube 1 and 4
when the csf is xanthochromic or grossly bloody
What tube do we count first for CSF
4
what tube do we used to perform cell count
4 if clear
When do we perform cell count on tube 4
when RBCs is >/10 or WBC >/4
when do prepare cytospin (differential) for cell count
if WBCs is >4
where is CSF produced
in choroid plexus
how are the malignant cells in CSF called
choroid plexus
what’s the function of CSF
provides nutrients to css
moves metabolic waste
mechanical barrier to cushion
Whats require for CSF samples
total volume
clarity/clot
what do we do we bloody CSF
spin down, if it does not clear is xathochromic
When do we perform WBC count on normal CSF
when heme or Onco patient
when do we perform cell count in tube 2 for CSF
leukemia/cancer
when do we perform cell count in tube 3 for CSF
to rule out meningitis
What does xanthochromsia indicates
traumatic tap, intracerebral or subarachnoid hemorrhage
How do we perform a cell count in CSF
1 drop of albumin + 2 or 3 drops of CSF
What cells can we see in CSF
Neutrophil, Lymph, Eso, baso, Mono macro
a macro/mono with iron in the cytoplasm
hemosiderin
characteristic of choroid plexus
clumping larger than normal dark color phagocytosis bledding
