10+ Medical Laboratory Technician Interview Questions and Answers for Freshers

Anticoagulant is a substance that prevents blood from clotting. Natural anticoagulant example is heparin.

• Anticoagulant is a substance that inhibits the clotting of blood.

• It is commonly used in medical procedures to prevent blood clots.

• Heparin is a natural anticoagulant found in the body.

• Other examples of natural anticoagulants include antithrombin and protein C.

The WHO recommended haemoglobin estimation method is the cyanmethemoglobin method.

• The cyanmethemoglobin method involves converting hemoglobin to cyanmethemoglobin, which is then measured spectrophotometrically.

• This method is considered to be the gold standard for hemoglobin estimation.

• It provides accurate and reliable results.

• Other methods like the Sahli's method or the Hemocue method may also be used, but the cyanmethemoglobin method is recommended by the WHO.

Tests for fungal infection in patients

• Collect samples from the affected area

• Perform a fungal culture test

• Conduct a microscopic examination of the sample

• Perform a blood test to detect fungal antibodies

• Use PCR (polymerase chain reaction) to detect fungal DNA

• Perform a skin test to check for an allergic reaction to fungal antigens

I manage lab quality by implementing quality control measures, ensuring accuracy of tests, and following standard operating procedures.

• Implementing quality control measures such as daily calibration of equipment

• Ensuring accuracy of tests by following proper protocols and techniques

• Following standard operating procedures to maintain consistency and reliability

• Regularly reviewing and updating procedures to meet industry standards

The blood will turn brownish yellow after adding n/10 HCl.

• n/10 HCl is a dilute hydrochloric acid solution

• The acid helps to break down the blood cells and release hemoglobin

• The color change is due to the formation of acid hematin

• The test is used to detect the presence of blood in a sample

The best for your healthcare is to prioritize preventive measures and maintain a healthy lifestyle.

• Prioritize preventive measures such as regular check-ups and screenings

• Maintain a healthy lifestyle through exercise and balanced diet

• Avoid unhealthy habits such as smoking and excessive alcohol consumption

Yes, serum is the clear, yellowish fluid that remains after blood has clotted.

• Serum is obtained by allowing the blood to clot and then removing the clot and the blood cells.

• It contains various proteins, electrolytes, hormones, and antibodies.

• Serum is used in various diagnostic tests to detect the presence of certain substances in the blood.

• Examples of tests that use serum include liver function tests, lipid profile, and hormone assays.

The lifespan of red blood cells (RBCs) is approximately 120 days.

• Red blood cells have a finite lifespan and are constantly being replaced by new cells.

• The average lifespan of RBCs is around 120 days, but it can vary slightly between individuals.

• After 120 days, old and damaged RBCs are removed from circulation by the spleen and liver.

• The production of new RBCs occurs in the bone marrow to maintain a constant supply.

• Certain medical conditions or disorders can affect the lifespa...read more

PT INR stands for Prothrombin Time International Normalized Ratio, a test used to measure how long it takes for blood to clot.

• PT INR is a test used to monitor the effectiveness of blood-thinning medications like warfarin.

• It is calculated by dividing the patient's PT by the average PT of a healthy population, raised to the power of the International Sensitivity Index (ISI).

• A normal PT INR value is typically between 2.0 and 3.0, but this range may vary depending on the reason f...read more

ESR stands for erythrocyte sedimentation rate, which measures the rate at which red blood cells settle in a tube over time.

• ESR is a blood test used to detect inflammation in the body

• It is a non-specific test and can be elevated in various conditions such as infections, autoimmune diseases, and cancer

• The test involves measuring the distance that red blood cells settle in a tube of blood over a period of time

• A higher ESR value indicates more inflammation in the body

Normal fasting levels refer to the range of blood glucose levels after an overnight fast.

• Normal fasting blood glucose levels range from 70-99 mg/dL

• Levels above 126 mg/dL indicate diabetes

• Levels between 100-125 mg/dL indicate prediabetes

• Fasting levels may vary depending on age, gender, and other factors

Serum is the clear, yellowish fluid that remains after blood has clotted and the clot has been removed.

• Serum is the liquid part of blood that does not contain cells or clotting factors.

• It contains electrolytes, hormones, antibodies, and other proteins.

• Serum is used in medical testing to diagnose diseases and monitor treatment.

• Examples of serum tests include electrolyte panel, liver function tests, and lipid panel.

• Serum can also be used in research to study biomarkers and dise...read more

The erythrocyte sedimentation rate (ESR) measures how quickly red blood cells settle at the bottom of a test tube.

• ESR is a non-specific test used to detect inflammation in the body

• It is also known as the sedimentation rate (sed rate) or the Biernacki Reaction

• The test involves measuring the distance that red blood cells fall in one hour

• A higher ESR indicates more inflammation in the body

• ESR is commonly used to monitor conditions such as rheumatoid arthritis and infections

HB stands for Hemoglobin, a protein in red blood cells that carries oxygen throughout the body.

• HB is measured in blood tests to determine the amount of hemoglobin in the blood.

• Low levels of HB can indicate anemia, while high levels can indicate dehydration or other conditions.

• HB levels can be affected by factors such as age, gender, altitude, and smoking.

• Normal HB levels for adult men are between 13.5 and 17.5 grams per deciliter, and for adult women between 12.0 and 15.5 gra...read more

The lifespan of RBCs is approximately 120 days.

• RBCs are constantly being produced and destroyed in the body

• The average lifespan of RBCs is determined by the rate of production and destruction

• Factors such as age, health, and medical conditions can affect RBC lifespan

• RBCs are removed from circulation by the spleen and liver

• New RBCs are produced in the bone marrow

Leukocytes are also known as white blood cells (WBC).

• Leukocytes are the cells of the immune system that help fight infection and disease.

• There are different types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils.

• White blood cells are produced in the bone marrow and are found circulating in the blood and lymphatic system.

• An abnormal white blood cell count can indicate an underlying health condition.

• Examples of conditions that can ...read more
