Q & A

What is the normal oxygen binding capacity of 1g hemoglobin?

The oxygen binding capacity of 1g hemoglobin is 1.34 mL.

What is the normal value of serum total bilirubin?

The normal value of total bilirubin in serum is approximately 0.2 to 1.2 mg/dL.

What is the purpose of the GAD's test in urine?

The GAD's test in urine is done to detect the presence of ketone bodies.

What does the HBA1C test measure?

The HBA1C test is used for assessing blood glucose levels over a prolonged period.

What is the most common sugar found in semen?

Fructose is the main sugar found in semen.

What is the normal range for HDL cholesterol levels in serum?

Normal HDL levels in serum typically range between 40 to 60 mg/dL.

What is the key feature of the 'minor cross matching' procedure in blood banks?

In minor cross-matching, mixing is done between the patient's serum and the donor's red blood cells.

What is the role of albumin in the human body?

Albumin plays a crucial role in maintaining osmotic pressure in the blood, helping to keep fluid from leaking out of blood vessels.

Which bacteria is responsible for causing tuberculosis meningitis?

Tuberculosis meningitis is caused by Mycobacterium tuberculosis.

What is the function of the spectrophotometer in medical testing?

The spectrophotometer works based on the Beer-Lambert law, which relates absorbance to the concentration of a substance in solution.
