Unit 1-Diagnosis and Treatment of
Disease/Disorders Human Disease
Diagnosis - ANSthe identification of disease conditions
Medical History and Physical Exam - ANSThe first step in diagnosing illness is to have a your
doctor review your medical history and conduct a physical exam
Medical History - ANSIncludes information about your current health, including current physical
problems, your past health including prior medical concerns, family history of disease,
Environmental exposure that may have put you at risk.
Physical Exam - ANSTo evaluate overall health. The doctor focus on areas of concern. Doctor
may also order additional diagnostic testing
Blood tests - ANSBlood tests analyze the components of your blood and anything carried in the
plasma ( i.e. enzymes, proteins, sugars, etc.). Many different blood tests may be done
depending on what the suspected problem is
CBC ( complete Blood count) - ANS-most common- used to evaluate overall health. The teat
measures: -hemoglobin- allows RBCs to carry oxygen
-Hematocrit: the percentage of RBCs in the blood volume -White blood cells: fight infection
-Platelets: clotting
X-Ray( radiography) - ANSTake 2 dimensional pictures of your bones and internal organs.
CT( Computerized Tomography) - ANSAlso used X-rays, but provides more detailed images of
your organs than conventional x-rays do. X-ray tube rotates around the body to give
cross-sectional images of the body. Used to
-Locate and identify tumors
-Identify bone and joint damage
-Identify muscle and bone disorders
-Monitor disease like cancer or heart disease
MRI (magnetic resonance imaging) - ANSSimilar to CT, however it uses magnets and radio
waves instead of x-rays to generate the images of the inside of the body
-locate and identify tumors
-identify bone and joint damage
-Identify damage caused by heart disease
-Examine the nervous system in detail
