1
Q

Acid Phosphatase (PAP)

A

enzyme is present minimally in many tissues but 100 times higher in the prostate than any other tissue. it is also found in seminal fluid. it is released into the blood stream in metastatic carcinoma of the prostate, when the capsule breaks

2
Q

increased acid phosphatase

A

prostatic carcinoma**
any carcinoma metastasis to bone
hyperparathyroidism

3
Q

prostate specific antigen (PSA)

A

enzyme which is localized in normal prostatic epithelial cells and prostatic carcinoma cells. 80% of men with prostatic carcinoma have a significant increase in PSA
best prognostic indicator for monitoring reoccurance of cancer and best to detect effectiveness of therapy

4
Q

PSA and acid phosphatase

A

increases early detection of prostatic cancer

5
Q

what is the most reliable test for prostate cancer?

A

digital rectal exam

6
Q

A/G ratio

A

represents serum albumin level divided by the serum globulin level; approximately 2:1
reversed in multiple myeloma

7
Q

Alkaline phosphatase

A

enzyme found in many tissues, especially bone and liver. it is termed alkaline because this enzyme functions best at a pH of 9, and is associated with liver and osteoblastic activity. children normally have an alkaline phosphatase value 5 times that of your average healthy adult

8
Q

alkaline phosphatase is increased in

A

osteoblastic lesions (broken bone, liver), hepatic disease, hyperparathyroidism

9
Q

amylase

A

pancreatic enzyme that splits starch. high values often indicate pancreatitis. most common cause of pancreatitis are alcoholism and cholelithiasis

10
Q

amylase is increased in

A

acute pancreatitis

11
Q

ANA (FANA)

A

fluorescent antinuclear antibody test is used to demonstrate the presence of antibodies that lead to the production of the LE cell. there are two ANA that are significant in SLE (anti-DNA and anti-DNP

12
Q

anti-DNP

A

usually present in patients with various collagen diseases

13
Q

anti-DNA

A

strong evidence for the presence of SLE

14
Q

ANA (FANA) results

A

positive doesn’t definitely indicate SLE

a negative definitely rules it out

15
Q

ASO titre

A

one of a group of serologic procedures that demonstrates that the patient has reacted to an infection by group A streptococci. It measures the amount of antibodies present

16
Q

ASO titre increase in

A

acute glomerulonephritis

rheumatic fever

17
Q

BUN

A

chief end product of amino acid metabolism, formed by the liver. it is excreted in urine and comprises of about 1/2 of urinary solids

18
Q

BUN increased in..

decreased..

A

increased in renal disease

decreased in hepatic disease

19
Q

calcium (serum)

A

calcium, as well as phosphorus, are stored in the bone and are constantly exchanged with blood and tissue fluids: vitamin D and parathromone influence this process. vitamin D is needed to intestinal absorption of calcium. parathromone increases the rate of bone destruction with mobilization of calcium and phosphorus from bone. 99% of the calcium in the body is found int eh bones and teeth. the ionized form of calcium functions in the activation of enzymes in the blood clotting, in muscle contraction and in the transmission of nerve impulses. a decreased serum level causes tetany

20
Q

increased calcium in

decreased in..

A

hyperparathyroidism, bone metastasis

hypoparathyroidism, acute pancreatitis, renal failure

21
Q

CPK

A

present almost exclusively in skeletal muscle, heart muscle, and in brain tissue. it enters the circulation quickly after atrophy or necrosis of the cells. it is one of the most valuable tests to indicate the occurrence of an MI
CK-MB (heart attack), CK-BB (stroke), CK-MM (muscular dystrophy)

22
Q

creatinine

A

end product of the normal metabolism of phosphocreatine usitilized for muscle energy. it is a nitrogenous compound secreted in the urine. this level does not vary with diet, so it is a very valuable indicator of kidney function

23
Q

increased creatinine in

decreased in

A

increased in renal disease

decreased in muscular dystrophies

24
Q

CRP

A

not normally present in a patient’s blood. it appears in the presence of inflammation and is an earlier indicator of inflammation than an ESR. it is best used to evaluate the course and severity of tissue necrosis

25
Q

CRP present in..

A

rheumatoid arthritis, malignancy, infections

26
Q

ESR

A

refers to the amount of RBCs that fall to the bottom of a test tube in one hour. inflammation and necrosis of the tissue causes RBCs to aggregate and become heavier. the heavier the cell, the faster it falls. the cells are made heavier by proteins produced by the body in inflammatory states

27
Q

ESR increased in

A

multiple myeloma
temporal arteritis
collagen diseases

28
Q

glucose (blood)

A

blood sugar is formed from carbohydrates and stored in the liver as glycogen. slight elevations are said to be of questionable significance. this test is done in the fasting state is diagnostic of diabetes mellitus if 2 consecutive fasting blood sugar tests are over 140 mg%

29
Q

glucose (CSF)

A

CSF glucose is usually 60% of blood glucose. blood glucose is drawn 1 hour prior to a spinal tap. changes in blood sugar are seen in the CSF 1-3 hours later

30
Q

glucose (CSF) decreased in

A

meningitis

31
Q

increased protein, normal glucose in CSF

A

viral meningitis

32
Q

meningitis s/s

A
stiff neck (nuchal rigidity)
Kernig/Brudzinski
photophobia
worst headache of life
fever (bacterial=high)
33
Q

GGT

A

enzyme found mainly in liver, kidney, spleen, prostate. enzyme is normally higher in males because of large amounts found in the prostate. test is used to determine liver cell dysfunction and alcohol induced liver disease

34
Q

GGT is more sensitive in detecting

A

obstructive jaundice, cholangitis, cholecystitis

35
Q

glycosylated hemoglobin (hemoglobin A1C)

A

test of RBCs that reveals the body’s ability to utilize glucose over a period of 2-3 months. it is used only to evaluate the efficiency of insulin when controlling the blood sugar level
