Medical Laboratory Techniques Department Exam

Ultraviolet and Visible Light Ranges

• Ultraviolet light range spans from 100 to 185 nm.
• Visible light range extends from 3000 to 15000 nm.

Microbiological Techniques

• Shaking water baths are utilized in microbiology to ensure liquid-grown cell cultures mix continuously with air.

pH and pOH Relationship

• A solution with a pH of 10 corresponds to a pOH of 4, indicating the relationship between these two measures of acidity and alkalinity.

Calculating pH

• A solution containing 0.00000001 moles of hydrogen per liter has a neutral pH of 7.

Ultra Microtome Usage

• An ultra microtome is instrumental in cutting ultrathin sections ranging between 40 and 100 microns.

Importance of Tissue Consistency

• The crucial factor for achieving thin sections in cutting is the consistency of the tissue sample.

Blood Glucose Level Measurement

• Blood glucose levels are quantified in mmol/L.

Type 2 Diabetes

• Type 2 diabetes is characterized by insufficient secretion of insulin in the body.

Essential Instruments for Section Cutting

• A variety of instruments are deemed essential for section cutting processes in laboratories.

Tissue Preparation for Microtome

• Before being cut by a cryo microtome, tissue samples must first be made hard by freezing.
