Top 10 Questions for Laboratory Tech Interview

1. Describe the process of preparing a blood sample for analysis?

• Collect the blood sample using a safe and appropriate method.
• Transfer the blood sample to a suitable tube, such as a serum or EDTA tube.
• Mix the blood sample gently to prevent clotting.
• Centrifuge the blood sample to separate the plasma or serum from the red blood cells.
• Transfer the plasma or serum to a clean tube or aliquot.

2. Explain how do you perform a urinalysis?

Visual Inspection

• Check the sample for color, clarity, and any visible particles or sediment.

Chemical Analysis

• Use dipsticks or test strips to measure the concentration of various substances, such as glucose, protein, bilirubin, ketones, and nitrites.
• Interpret the color change on the dipstick or test strip to determine the presence and concentration of the target substance.

Microscopic Examination

• Centrifuge the urine to concentrate any cellular material or sediment.
• Transfer a drop of the sediment onto a microscope slide and examine it under a microscope.
• Identify and count any cells, bacteria, or other microscopic elements present in the sample.

3. What are the different types of microscopy used in a laboratory?

• Bright-field microscopy: Transmits light through the specimen to create an image.
• Dark-field microscopy: Illuminates the specimen from the side to create a dark background and highlight details.
• Phase-contrast microscopy: Uses phase differences in the light passing through the specimen to create contrast.
• Fluorescence microscopy: Uses fluorescent dyes to label specific structures or molecules in the specimen.
• Electron microscopy: Uses a beam of electrons to create a high-resolution image.
