Intro Flashcards
It is the biochemical analysis of body fluids in support of the diagnosis and treatment of disease.
Clinical Chemistry
Father of clinical chemistry
Johann Florian Heller
Is the science of obtaining, processing and communicating information about the structure and composition of matter.
Analytical Chemistry
Is the use or application of instruments for observation, measurement or control.
It involves the operation of one or more instruments in carrying out laboratory tests.
Instrumentation
Is the study of chemical processes within and relating to living organisms.
Biochemistry
Is the study of hormones and endocrine glands and organs.
Endocrinology
Test for presence and absence
Qualitative
Test for exact amount and numbers
Quantitative
Biologic specimens
• Blood
• Urine
• CSF
• Amniotic fluid • Synovial fluid
• Pleural fluid
• Peritoneal fluid
• Pericardial fluid
Has anticoagulant, fibrinogen and other clotting factors
Plasma
Free from clotting factors used to form the blood clot found at the bottom
Serum
Which is preferred in cc plasma or serum, why
Serum because plasma has anticoagulant like KEDTA which becomes an interference. And plasma has fibrinogen
Is the preferred sample for clinical chemistry
testing.
It removes the unwanted red blood cells
more efficiently, generating more sample
volume per unit of blood.
Serum
• Is suitable for tests that evaluate kidney function, since it contains waste products excreted by the kidneys.
• It is also often used in toxicology.
Urine
Is the liquid that surrounds the brain and spinal cord.
Cerebrospinal fluid
Where is CSF located
Between arachnoid and pia matter referred to as subarachnoid space
Where is CSF found?
Brain inside ventricles
When do doctors test for CSF?
Possible case of meningitis
How is CSF obtained
Spinal tap or lumbar puncture usually at the interspace of vertebrae L3 to L4
Amniotic fluid is the fluid that cushions the baby, found in the amniotic sac. It is obtained through?
Transabdominal amniocentesis
Lubricant for the joints and transport medium for delivery of nutrients and removal of cell wastes
Synovial fluid
Doctors ask for synovial fluid for testing if the doctor suspects that a patient has……. Accomplished by
Athritis, Gout for uric acid…. Athrocentesis
Resembles serum appears yellowish
Serous body fluids
Found in our lungs or thoracic cavity
Pleural fluid
Found in heart
Pericardial fluid
Found in the abdomen specifically peritoneum the membrane that protects internal organs
Peritoneal fluid
Presence of excess peritoneal fluid
Ascites
Peritoneal fluid is Obtained by
Paracentesis
Are positive meaning they are cations
Sodium and potassium
have a part in neuromuscular
activity because they are positively charged.
Calcium and magnesium
Its clinical significance in our body is to maintain blood pressure and increased during dehydration, usually if vomiting and diarrhea this is excreted
Sodium
Responsible for the muscle contraction of your body
Potassium
Most commonly found in sweat and individual who has thyroid problem
Chloride
