Study Notes

Examination of Stool and Molecular Biology

Routine fecalysis examines stool for pathologic conditions.
DNA and RNA identification techniques are significant in detecting diseases.
Polymerase Chain Reaction (PCR) is a widely used method for genetic analysis.

Blood Bank and Laboratory Testing

The Blood Bank, also known as Immunohematology, is critical in clinical laboratories.
Faulty cross-matching can lead to severe consequences, including patient death.
Blood typing and compatibility testing form the backbone of Blood Bank services.

Laboratory Testing Cycle

The laboratory testing cycle begins with a doctor's request and ends with result generation (Turn-around Time).
Quality Control (QC) programs ensure accuracy in laboratory results.
Internal Quality Control programs continuously assess laboratory personnel competency.

Mycology, Virology, and Hematology

Mycobacteriology involves fungal sensitivity testing and culture.
Mycology focuses solely on fungi identification, while Virology identifies viruses.
Hematology encompasses cell enumeration in blood and other body fluids (e.g., CSF).

Historical Figures in Medical Technology

Anton van Leeuwenhoek (1632-1723) is considered the Father of Microbiology; he discovered red blood cells and classified bacteria.
His advancements with the compound microscope spurred growth in microbiology and pathology.
Marcello Malpighi (1628-1694) is known as the Father of Pathology; he contributed to embryology and anatomy.

Morphology in Microbiology

Morphology refers to the study of bacterial shapes and classification.
Cocci are round-shaped bacteria, while rods are elongated shapes.

Medical Technology in the Philippines

The introduction of medical technology in the Philippines occurred post-World War II by the 26th Medical Infantry of the US Army.
They established the first clinical laboratory at Quiracada St., Sta.
