Q

Which component of CBC determines the percentage of packed RBC in whole blood?

A

Hematocrit

18
Q

Under Hematocrit determination, plasma and blood cells are separated by:

A

Centrifugation

19
Q

Under Hematocrit determination, what is being measured after centrifugation as it could indicate whether the body is producing less or too much RBCs?

A

Height of RBC Column

20
Q

It is a component of CBC which is used to evaluate bleeding disorders, bone marrow diseases, and excessive clotting disorders?

A

Platelet or Thrombocyte Count

21
Q

This component of whole blood plays a crucial role/function in the coagulation of blood.

A

Platelets or Thrombocytes

22
Q

When a patient is diagnosed with dengue fever, he or she is likely to have (increased, decreased) platelet count.

A

Decreased

23
Q

The determination of various coagulation factors is performed under:

A

Coagulation Studies

24
Q

These are proteins circulating in the blood that are essential for proper blood clot formation.

A

Coagulation Factors

25
Q

‘PT’ under Coagulation Studies stands for:

A

Prothrombin Time

26
Q

‘aPTT’ under Coagulation Studies stands for:

A

Activated Partial Thromboplastin Time

27
Q

True or False

Aside from PT and aPTT, Coagulation Studies may also encompass the assessment of blood clotting functions in patients.

A

True

28
Q

What is the most commonly used specimen in the Clinical Chemistry Section of a Clinical Laboratory?

A

Serum

29
Q

True or False

Blood to which an anticoagulant has been added will clot.

A

FALSE

Blood + Anticoagulant = UNCLOTTED BLOOD

30
Q

True or False

If a blood is mixed with an anticoagulant, blood cells will settle to the bottom of the tube leaving serum at the top of the tube.

A

FALSE

Blood + Anticoagulant = UNCLOTTED BLOOD = PLASMA

31
Q

When blood to which an anticoagulant has been added does not exhibit clotting, it would eventually form three layers. Which among these three would contain WBCs and platelets?

A

Middle Layer, BUFFY COAT

32
Q

True or False

Blood to which NO anticoagulant has been added will clot.

A

TRUE

33
Q

True or False

In a clotted blood, blood cells get caught in the clot which leaves plasma behind.

A

FALSE

CLOTTED BLOOD = SERUM

34
Q

Which analyte is a product of carbohydrate metabolism which serves as the chief source of energy for living organisms?

A

Glucose

35
Q

Utilization of glucose is controlled by which hormone?

A

Insulin

36
Q

Fasting Blood Sugar requires which type of blood specimen?

A

Fasting Specimen

37
Q

Ideal fasting hours for FBS testing.

A

10 hours

38
Q

Which test under the Clinical Chemistry section is used to screen for hyperglycemia and hypoglycemia; to help in the diagnosis of diabetes mellitus; and to monitor glucose levels in persons with diabetes?

A

Fasting Blood Sugar (FBS)

39
Q

What are the three analytes that play relative clinical significance in Renal Function Tests?

A

Urea, Creatinine, and Uric Acid

40
Q

It is considered as the end product of protein metabolism that is normally cleared from the blood by the kidney into the urine.

A

Urea

41
Q

It is formed by the breakdown of creatine during muscle metabolism.

A

Creatinine
