Winston Engineering Interview Questions and Answers

Dilution is required when a sample is too concentrated to accurately measure, or when a specific concentration is needed for testing.

• Dilution is necessary when the sample is too concentrated for accurate results.

• It is also done to achieve a specific concentration needed for testing.

• Dilution factors are calculated based on the initial and final concentrations.

• Common examples include diluting blood samples for cell counting or urine samples for chemical analysis.

Antibiotics used for GNB include ciprofloxacin, levofloxacin, and meropenem.

• Ciprofloxacin

• Levofloxacin

• Meropenem

AFB staining is a laboratory technique used to detect acid-fast bacteria, such as Mycobacterium tuberculosis.

• Prepare a smear of the specimen on a slide

• Fix the smear with heat or alcohol

• Stain the smear with carbol fuchsin

• Decolorize with acid-alcohol

• Counterstain with methylene blue

• Examine under a microscope for red acid-fast bacilli

AMH test is a blood test used to measure the level of anti-Mullerian hormone in the body, which can help assess ovarian reserve and fertility potential.

• AMH test is commonly used in fertility clinics to assess ovarian reserve in women.

• It can help predict a woman's response to fertility treatments like IVF.

• Low AMH levels may indicate a decrease in ovarian reserve, while high levels may indicate polycystic ovary syndrome (PCOS).

Westgard rule is a quality control tool used in medical laboratories to detect errors or outliers in test results.

• It is a set of rules used to evaluate the quality of laboratory test results.

• It helps in detecting errors or outliers in test results.

• It is named after Dr. James O. Westgard, who developed this tool in the 1970s.

• There are different types of Westgard rules, such as 1s, 2s, R4s, and 4:1s.

• For example, the 1s rule flags a result as an outlier if it is more than 1 stan...read more

Quality control is a process of ensuring that the results of laboratory tests are accurate and reliable.

• It involves monitoring and verifying the accuracy and precision of laboratory equipment and procedures.

• It includes the use of control samples to ensure that the results obtained are within acceptable limits.

• It also involves identifying and correcting errors or problems that may affect the quality of the test results.

• Examples of quality control measures include running contr...read more
