3. TYPES OF SPECIMEN

4. TYPES OF SPECIMEN

5. 1. BLOOD SPECIMEN
 Blood specimen is a small sample of blood collected for analysis,
and often used in medical diagnosis to assess various health
parameters such as complete blood count,chemistry and disease
markers.
 This sample is typically extracted through Venipuncture Or
finger stick technique.
 It contains a wealth of information that can aid in diagnosing
and monitoring various medical conditions.

6. BLOOD SPECIMEN CONTND.…
 One of the primarily Components analyzed in a blood specimen is the CBC,
which assess the quantity and quality of different blood cells.
 Additionally the blood chemistry panel examines the levels of various
substances like glucose, electrolytes and enzymes.

7. BLOOD SPECIMEN CONTND.…

for blood gas analysis to assess oxygen and carbon
dioxide levels.
