Term
When doing liver enzyme tests, is ALT or AST specific to the liver?
Definition
ALT
Term
A marked (>1000) increase in aminotransferases (ALT and AST) suggests this
Definition
Toxin/drug induced hepatitis, acute viral hepatitis, liver ischaemia
Term
A modest (300-500) increase in aminotransferases (ALT and AST) suggests this
Definition
Chronic/autoimmune/alcoholic hepatitis, biliary obstruction
Term
A mild (<300) increase in aminotransferases (ALT and AST) suggests this
Definition
Cirrhosis, non-alcoholic fatty liver disease, haemochromatosis
Term
A ratio of ALT:AST where ALT>AST suggests this
Definition
Chronic liver disease
Term
A ratio of ALT:AST where ALT
Definition
Establishes cirrhosis (smaller difference), alcoholic liver disease (bigger difference)
Term
A marked increase (>4x normal) in ALP suggests this
Definition
Cholestasis (gallstones, pancreatic CA, drugs)
Term
A marked increase (<3x normal) in ALP suggests this
Definition
Hepatitis, cirrhosis, infiltration (hepatocellular CA)
Term
This mirrors ALP and so can be used to confirm if a rise in ALP is of hepatic origin
Definition
Gamma-glutamyltransferase (yGT)
Term
Unconjugated hyperbilirubinaemia (indirect bilirubin fraction >85%) suggests this
Definition
Increases RCC breakdown (haemoliytic anaemia), impaired hepatic uptake (drugs, CFF), impaired conjugation
Term
Conjugated hyperbilirubinaemia (direct bilirubin fraction >50%) suggests this
Definition
Hepatocellular dysfunction (liver diseases), impaired hepatic secretion (cholestasis)
Term
You would find low albumin + high protein in these cases
Definition
Advanced cirrhosis, alcoholism, protein malnutrition, chronic inflammation
Term
You would find low albumin + normal protein in these cases
Definition
Infection (negative acute phase reactant)
Term
You would find high albumin + high protein in these cases
Definition
Myeloma
Term
What prothrombin time/INR would you expect to see in liver disease?
Definition
Raised
Term
Urine dipstick - high specific gravity suggests this
Definition
Dehydration, proteinuria, renal artery stenosis
Term
Urine dipstick - low specific gravity suggests this
Definition
Diabetes insipidus, renal failure, excess hydration
Term
Urine dipstick - alkaline urine suggests this
Definition
Systemic - vegetarian/low carb diet
Local - UTI, renal tubular acidosis
Term
Urine dipstick - acidic urine suggests this
Definition
Systemic - acidosis, starvation, diarrhoea
Acidic diet - high protein, cranberry
Term
Haematuria suggests this
Definition
Neoplasm, obstruction, trauma, inflammation (UTI)
Term
Haemaglobinuria suggests this
Definition
Intravascular haemolysis, burns, pre-eclampsia, sickle cell crisis, multiple myeloma
Term
Increased protein in urine could be a sign of this
Definition
Nephrotic syndrome, glomerulonephritis, renovascular disease, myeloma, UTI
Term
Nitrites in the urine are suggestive of this
Definition
Gram negative UTI
Term
Ketones in urine are suggestive of this
Definition
Starvation, low carb diet, diabetes/DKA, alcoholism, pregnancy, hyperthyroidism
Term
Glucose in the urine is suggestive of this
Definition
Diabetes mellitus, Cushings, thyrotoxicosis/acromegaly
Term
Increased urobilinogen is found in these cases
Definition
Haemolytic anaemia, malaria
Term
Decreased urobilinogen is found in these cases
Definition
Bile duct obstruction
Term
High pH, low CO2, normal HCO3-, and high O2
Definition
Hyperventilation
Term
Normal pH, high CO2, high HCO3-, and low O2
Definition
Stable, chronic COPD
Term
Low pH, very high CO2, high HCO3-, and very low O2
Definition
Acute COPD exacerbation
Term
Increased pH, low CO2, normal HCO3-, normal or elevated O2
Definition
Asthma exacerbation
Term
Low pH, high CO2, normal HCO3-, low O2
Definition
Decreased respiratory drive (life threatening asthma, opiate overdose)
Term
Normal pH, CO2, and HCO3-, but low O2
Definition
Pulmonary fibrosis
Term
High pH, low CO2, normal HCO3-, low O2
Definition
Pulmonary embolism
Term
Microcytic anaemia causes
Definition
Thalassemia, anaemia of chronic disease, iron deficiency
Term
Normocytic anaemia causes
Definition
Haemolytic, ifiltrative, acute bleeding
Term
Macrocytic anaemia, megaloblastic causes
Definition
B12 or folate deficiency
Term
Macrocytic anaemia, non-megaloblastic causes
Definition
Alcohol, reticulocytosis, liver disease, pregnancy
Term
Microcytic anaemia causes
Definition
Lead poisoning, siberoblastic
Term
Normocytic anaemia causes
Definition
Renal failure, aplastic, anaemia of chronic disease
Term
Anaemia, with abnormal WCC and platelet count
Definition
Likely a bone marrow cause
Term
Anaemia with raised reticulocytes
Definition
Blood loss or haemolytic anaemia
Term
