Which of the following Is used to determine the total number of white blood cells In urine?

Rationale

Microscope is used to determine the total number of white blood cells in urine.

The microscope allows for the direct visualization and counting of white blood cells present in a urine sample, providing an accurate assessment of cellular components.

A (Chemical test strip) YOUR ANSWER

Chemical test strips are designed to detect specific substances in urine, such as glucose, protein, or pH levels, but they do not provide a direct count of cells. While they can indicate the presence of abnormalities, they cannot quantify white blood cells.

B (Microscope) CORRECT

The microscope enables the examination of urine samples at a cellular level, allowing for the identification and counting of white blood cells. This method is crucial for diagnosing infections or other medical conditions by evaluating the number of these cells in the urine.

C (Refractometer) YOUR ANSWER

A refractometer measures the concentration of solutes in a liquid by assessing how light is bent as it passes through the sample. While it is helpful in determining urine specific gravity, it does not provide any information about the cellular composition, including white blood cell counts.

D (Urinometer) YOUR ANSWER

A urinometer is used to measure the specific gravity of urine, similar to a refractometer. While it provides valuable information about urine concentration, it does not analyze or count white blood cells, making it unsuitable for this purpose.

Conclusion

To accurately determine the total number of white blood cells in urine, the microscope is the essential tool since it allows for direct observation and counting of these cells. Other options, such as chemical test strips, refractometers, and urinometers, serve different purposes and do not provide the necessary cellular analysis required for assessing white blood cell levels.
