Which results should be repeated before they are investigated
What the pivotal programmes measured and how often, which is a more defensible template than most published monitoring schedules.

Which results are findings and which are consequences of the weight loss
The estimated glomerular filtration rate is calculated from creatinine, creatinine comes from muscle, and muscle mass is falling. The arithmetic is unforgiving.
Monitoring intervals, and the case against measuring too often
A panel that will not change a decision is a panel that generates work.
The out-of-range flag is a statistical convention with a printer attached
The arithmetic of the reference change value, worked for the analytes that matter here.
The out-of-range flag is a statistical convention with a printer attached
Almost every misreading of a laboratory panel is a misunderstanding of what a reference interval is and how much a result has to move before the movement means anything.
What a low result means when intake has halved
What the trials measured, which in the case of micronutrients is very little.
What the upper limit of normal for ALT should be, and why it is not
Asymptomatic pancreatic enzyme elevation is common on treatment and is not pancreatitis. The distinction is clinical, not biochemical.
HbA1c and its lag: what a result three months old is telling you
HbA1c integrates roughly three months of glycaemia with the most recent weeks weighted most heavily. Almost every misreading of it is a misreading of that weighting.
Reading HbA1c in the presence of anaemia
The alternatives with shorter windows, what they measure, and why they are rarely ordered.
What the outcome trials measured in the kidney
Asymptomatic pancreatic enzyme elevation is common on treatment and is not pancreatitis. The distinction is clinical, not biochemical.
What has to change before a change has happened
A flag is a probability statement about a population. It is not a statement about the person holding the printout.
