Anti-coagulant used to treat blood clots, blocks the enzyme vitamin K epoxide reductase which inhibits vitamin K dependant clotting factors. Very important to have INR checked regularly. If you miss a dose DO NOT double dose.

A

It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled

 Non-specific marker
 Substance produced by the liver and increases in the presence of
inflammation

39

 IBD
 Certain cancers
41
Q

ESR

A

A type of blood test that measures how quickly erythrocytes settle at the bottom of a test tube that contains a blood sample. Normally they settle quite slowly, a faster than normal rate may indicate some sort of inflammation.

42
Q

Malignant causes of ↑ ESR

A
  • malignant lymphoma

- carcinomas of colon and breast

43
Q

Haematological causes of ↑ ESR

A
  • multiple myeloma

- anaemia of acute or chronic disease combined with iron deficiency anaemia ( not iron deficiency anaemia alone)

44
Q

Connective tissue disorder ↑ ESR

A
  • SLE
  • Rheumatoid arthritis
  • Polymyalgia rheumatic
  • Temporal arteritis
45
Q

Infections that ↑ ESR

A
  • TB
  • Acute hepatitis
  • bacterial
46
Q

Name 7 components of LFTs

A
  1. Albumins
  2. Globulins
  3. ALP
  4. GGT
  5. AST or ALT
  6. Bilirubin
  7. Liver enzymes
47
Q

Causes of high albumin

A
  • Severe infections
  • Severe dehydration
  • Chronic inflammatory diseases,
  • Hepatitis
48
Q

Causes of low albumin

A
  • Malnutrition e.g. crohn’s, coeliac disease
    – kidney disease
  • Liver disease e.g. hepatitis, cirrhosis
49
Q

Causes of ↑ ALP

A

Bile duct obstruction stimulates ALP synthesis so raised in:

  • Obstructive liver disease
  • Increased osteoblastic activity
50
Q

When is bilirubin high?

conjugated vs unconjugated

A

high conjugated = liver or bile duct disease

high unconjugated = Gilbert’s or haemolytic anaemia

51
Q

Tumour markers

A

Substances that are found at higher than normal values in the blood, urine and tissue of a person with cancer.

52
Q

Uses of tumour markers

A
  1. Screen for cancers early on in people at high risk
  2. Chance of recurrence of a cancer
  3. Chance of recovery
  4. Response to treatment
  5. Guide treatment decisions
53
Q

Problems with tumour markers

A

 A condition or disease other than cancer can increase tumour marker levels.
 Some tumour marker levels may be high in people without cancer
 Tumour marker levels may vary over time, making it hard to get consistent results

54
Q

Carcinoembryonic antigen (CEA)

  • Normal range?
  • What is it?
  • What are the uses?
A
  • The main use of CEA is as a tumour marker, especially with intestinal cancer (particularly colorectal cancer), but can be used for lung , breast, liver cancer.
  • A rising CEA level indicates progression or recurrence of the cancer.
  • Normal = <2.5ng/ml in adult non-smoker
  • Normal = <5.0ng/ml in a smoker
55
Q

Prostate specific antigen (PSA)

  • Levels are high in?
  • Normal levels?
A 
Protein made by the prostate gland. 
No specific normal or abnormal level of PSA in the blood and levels may vary
over time in the same man.
Levels are high in:
– Men with prostate cancer
– Prostatitis
– Benign prostatic hyperplasia
56
Q

ADvantages of PSA

A

 It can help pick up prostate cancer before you have any symptoms
 It may help to pick up a fast-growing cancer at an early stage

57
Q

Disadvantages of PSA

A

 You may have a raised PSA level even if you do not have prostate cancer
 The PSA test may miss out prostate cancer
 If the PSA level is raised, you may need more tests e.g. biopsy which can
cause side effects such as pain, infection, blood in the urine

58
Q

How to explain what PSA is to a patient?

A

The PSA test is a blood test that measures the amount of prostate specific antigen (PSA) in your blood. PSA is a protein produced by normal cells in the prostate and
also by prostate cancer cells. It’s normal to have a small amount of PSA in your blood, and the amount rises as you get older and your prostate gets bigger. A raised
PSA level may suggest you have a problem with your prostate, but not necessarily cancer.

59
Q

Things to ask in HxPC of PSA

A

 I understand you are… and I can see from your results that your PSA levels are…….
 How much do you know about PSA and what it means?
 Just going to ask you some questions which will help me figure out why your results are the way they are
 How are you feeling today, Any symptoms at all?
Frequency, urgency, nocturia, haematuria, dysuria, hesitancy, straining, intermittent flow, poor stream, incomplete emptying, post micturition dribbling, incontinence.
