tests
TESTS
  • CBC: Complete Blood Count
  • Serum Chemistries
  • Liver Function/ Amylase
  • Lipids: Blood Fats
  • Immune System: CD4 & Viral Load
cbc complete blood count
CBC: Complete Blood Count
  • Red Blood Cells: RBC
  • White Blood Cells:WBC
  • Platelets: Plts
  • Serum/Plasma
bone marrow
Bone Marrow
  • All Blood Cells made in bone marrow.
  • Bone Marrow is the spongy centers of bones sometimes seen in cuts of meat
stem cells
Stem Cells
  • Stem cells are young cells
  • All blood cells start as stem cells
  • They get “drafted” as RBCs, WBCs or platelets depending on the body’s needs
red blood cells
Red Blood Cells
  • Called erythrocytes
  • “cytes” = cells
  • Shaped like bagel with hole covered over
  • Filled with hemoglobin that carries oxygen from the lungs to every cell in the body.

white blood cells
White Blood Cells
  • WBCs are disease fighters
  • Some make antibodies and some fight invaders directly
  • Divided into categories depending on function and what they look like.
types of white cells
Types of White Cells
  • Lymphocytes: B and T cells. Agranulocytes
  • Granulocytes: polymorphonucleocoytes mostly neutrophils (55-80%), also basophils and eosonophils
  • Monocytes: mature into macrophages (big eaters)

a cellular extension called a pseudopod

abbreviations
Abbreviations
  • RBC = Red Blood Cell
  • WBC = White Blood Cell
  • HCT = Hematocrit
  • Hbg = Hemoglobin
  • ANC = Absolute Neutrophil Count
tests of immune function
TESTS OF IMMUNE FUNCTION

A human cell infected with a rhinovirus ruptures,

relasing millions of new viruses

A human T-helper cell is under

attack by HIV virus

viral load tests
Viral Load Tests
  • PCR: Most common. Usually expressed has HIV-1 PCR in copies per milliliter. Roche Amplicor
  • bDNA: values are different. Usually ½ of PCR value
  • NASBA: nucleic acid sequence based amplification. Values are also different
undetectable viral load does not mean no virus present

UNDETECTABLE VIRAL LOAD DOES NOT MEAN NO VIRUS PRESENT

Remember: there are other places for virus to hide
