Question 1

What is the purpose of performing a routine test?

Accepted Answer

To assist in the early detection of disease

Question 2

What temperature is usually required for storing testing materials and performing laboratory tests?

Accepted Answer

Most laboratory tests and testing materials require storage and performance at room temperature unless specified otherwise, to ensure the integrity and accuracy of the test results.

Question 3

Detection of abnormal cells is known as

Accepted Answer

Cytology is the branch of biology concerned with the structure and function of plant and animal cells, including the detection of abnormal cells.

Question 4

All of the following are guidelines for storing specimens and testing components in a laboratory refrigerator except:

Accepted Answer

Checking the temperature of the refrigerator should be done daily, not just once each week, to ensure it remains within the required range for specimen and testing component storage.

Question 5

All of the following are reasons for indicating the clinical diagnosis on the laboratory request form except:

Accepted Answer

The source of the specimen is indicated on the laboratory request form to provide necessary information for processing and analysis, but it is not a reason for indicating the clinical diagnosis. Indicating the clinical diagnosis helps in alerting laboratory personnel to possible pathogens, assists in billing, and ensures the lab results are relevant to the provider's needs.

Question 6

All of the following are found in a laboratory directory except:

Accepted Answer

A laboratory directory typically includes information about the tests performed, patient preparation, specimen requirements, and handling/storage instructions, but it does not include instructions for testing specimens, which are usually found in procedure manuals or specific test protocols.

Question 7

What is a profile?

Accepted Answer

A profile in the context of laboratory testing refers to an array of laboratory tests that are grouped together to identify a disease or condition. This can include a series of blood tests, urine tests, or other biomarkers that collectively provide a comprehensive overview of an individual's health status or the presence of specific diseases.

Question 8

Which of the following is an example of using a laboratory test to assist in the differential diagnosis of a patient's condition?

Accepted Answer

Performing a strep test helps differentiate between strep throat and other causes of pharyngitis, aiding in the differential diagnosis.

Question 9

How are laboratory reports delivered to the medical office?

Accepted Answer

Laboratory reports can be delivered to a medical office through various methods including fax, mail, hand-delivery by a laboratory courier, and electronically. This ensures flexibility and efficiency in communication between laboratories and medical offices.

Question 10

The study of blood and the blood-forming tissues is known as

Accepted Answer

Hematology is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation.

Question 11

All of the following are included on a laboratory request form except:

Accepted Answer

Laboratory test results are not included on a laboratory request form because the form is used to request tests, not to report results. The other options (provider's name and address, patient's age and gender, date and time of collection, and source of the specimen) are standard information required to process and interpret the test accurately.

Question 12

All of the following are advantages of the laboratory component of an EMR program except:

Accepted Answer

The EMR (Electronic Medical Record) program does not determine the type of tests required by a patient; this decision is made by healthcare professionals based on the patient's condition and medical history. The other options (A, B, and D) are indeed advantages of the laboratory component of an EMR program, facilitating electronic requests, transmission, and tracking of laboratory tests.

Question 13

All of the following are included in a lipid profile except:

Accepted Answer

Glucose is not a lipid; it is a simple sugar and is typically measured in a blood glucose test, not a lipid profile. A lipid profile includes measurements of total cholesterol, HDL cholesterol, LDL cholesterol (not listed here), and triglycerides.

Question 14

Which of the following occurs when the body is in homeostasis?

Accepted Answer

Homeostasis refers to the state of steady internal, physical, and chemical conditions maintained by living systems. When the body is in homeostasis, its physiological parameters, such as those measured by laboratory tests, fall within the reference ranges that are considered normal or healthy.

Question 15

What is the purpose of the patient accession number found on the laboratory report?

Accepted Answer

The patient accession number is primarily used to uniquely identify each specimen in the laboratory, ensuring accurate tracking and processing.

Question 16

The study of antigen-antibody reactions to assess the presence of a substance or to determine the presence of disease is known as

Accepted Answer

Immunology and blood banking involve the study of the immune system, including antigen-antibody reactions, which are crucial for determining the presence of substances or diseases in the body.

Question 17

The purpose of patient preparation for a laboratory test is to

Accepted Answer

Patient preparation is crucial to obtaining a specimen that accurately reflects the patient's physiological state, thereby ensuring accurate test results.

Question 18

What is the purpose of a laboratory report?

Accepted Answer

The primary purpose of a laboratory report is to relay the results of laboratory tests to the healthcare provider, who can then interpret these results in the context of the patient's overall health condition and history.

Question 19

Which of the following is an example of using a laboratory test to regulate treatment?

Accepted Answer

Testing blood glucose levels to adjust insulin dosage is a direct example of using a laboratory test to regulate treatment, as the results directly influence the amount of medication administered.

Question 20

Which of the following assists the provider in making a diagnosis?

Accepted Answer

All of the options listed (health history, physical examination, laboratory tests, and diagnostic tests) are tools that assist healthcare providers in making a diagnosis. Each element provides critical information that contributes to understanding the patient's condition.
