4. WHAT WE ARE RECEIVE?
•Specimen
type
• Whole Blood
1. Plasma
2. Serum
• Body Fluid
1. Cerebro-spinal Fluid CSF
Cerebrospinal fluid (CSF) is a fluid that surrounds the brain
and spinal cord.
CSF acts as a cushion, protecting the brain and spine from
injury. The fluid is normally clear same as water.
6. Phlebotomist draws sample
1.Gentlly invert five times
To mix dot activator with blood
2. Allow blood to clot in a
vertical position
Observe a dense clot
