Laboratory Glasswares Quiz

Centrifuge Tubes

• Conical shape of graduated centrifuge tubes provides a pointed tip that allows for easy mixing and minimal sample loss.

Measuring Serum and Reagents

• Micropipettes are the most suitable glassware for measuring less than 1 mL of serum and reagents.

Pipettes

• The main purpose of a pasteur pipette is to accurately measure and transfer small volumes of liquids.
• An automatic pipette is used to accurately measure and dispense precise volumes of liquids.

Serum Collection

• Serum separator tubes are used to measure serum extracted from blood.

Containers and Specimens

• Glassware, such as test tubes, are generally used as containers for specimens and mixtures of samples and reagents during testing.

Evacuated Tube System

• The primary purpose of the evacuated tube system with color-coded rubber stoppers is to collect and store blood samples.

Syringes and Blood Collection

• In venous blood collection for Blood Banking tests, a 10 mL syringe is commonly used.

Evacuated Tubes

• An evacuated tube with a Lavender top is used to collect blood samples for hematology and clinical chemistry tests.

Glass Slides

• Plain glass slides are used in venous blood collection to prepare blood smears.

Clinical Centrifuge

• The primary function of a clinical centrifuge in the Blood Bank laboratory is to separate blood components and prepare samples for testing.

Water Bath

• The primary purpose of a water bath in the context of blood banking tests is to incubate and process blood samples at a controlled temperature.

Agglutination

• A test tube rack is specifically used to visualize antigen-antibody reactions for more accurate interpretation of results.

Refrigeration

• A blood bank refrigerator is specifically designed to store and preserve blood components at a controlled temperature, unlike a household refrigerator.

Sterilization

• The primary function of a clinical sterilizer in the context of Blood Banking tests is to sterilize equipment and materials.

Microscopy

• A compound microscope is used in Blood Banking tests to examine blood cells and detect abnormalities.

Serum Extraction

• A centrifuge is specifically used to extract the serum from clotted blood in the Blood Bank laboratory.

Specimen Collection

• Whole blood is the primary specimen collected in blood banking.

Red Cell Suspension

• Red cell suspension plays a critical role in blood banking testing procedures as it is used to detect antigen-antibody reactions.

Blood Transfusion Risks

• The most common cause of disaster in blood transfusion is ABO incompatibility.

Pre-Transfusion Testing

• A freshly drawn sample should be required before transfusion of type-specific products.

Indicator Cells

• Indicator cells are used in laboratory procedures to detect and display antigen-antibody reactions.
• 0.8% of red cell suspensions are universally employed as indicator cells for displaying antigen-antibody reactions.

Specimen Labeling

• Mislabeled, incompletely labeled, and unlabeled specimens should not be processed for transfusion to prevent errors and contamination.

Sample Requirements

• A serum sample is required if antibodies are subject for study in blood banking.

Safe Transfusion

• Proper identification and labeling of blood components are critical for safe transfusion.
