A prothrombin time (PT) test measures how long it takes for blood to clot. It’s a blood test that helps evaluate the ability of blood to clot normally.
What it measures
The time it takes for a blood sample to clot after adding chemicals
The function of clotting factors, which are proteins that help blood clot
Why it’s done
To diagnose bleeding or blood clotting disorders
To check if blood-thinning medications are working properly
How it’s done
A blood sample is drawn from a vein, usually in the arm or hand
Chemicals are added to the blood to see how long it takes for a clot to form
Results
Normal PT values are 10 to 14 seconds
The international normalized ratio (INR) is a calculation based on the PT result
Risks
Excessive bleeding
Hematoma (blood under the skin)
Infection at the puncture site
Feeling faint or soreness or pain at the site where blood was drawn

A random blood sugar (RBS) test measures the amount of glucose in your blood at any time of day. A normal RBS level depends on when you last ate, but is usually 125 mg/dL (6.9 mmol/L) or lower. A level of 200 mg/dL (11 mmol/L) or higher may indicate diabetes.
What’s normal?
Normal: A level of 125 mg/dL (6.9 mmol/L) or lower is usually normal
Prediabetes: A level between 140 and 199 mg/dL (7.8 and 11 mmol/L) is considered prediabetes
Diabetes: A level of 200 mg/dL (11 mmol/L) or higher may indicate diabetes
What can affect your results?
Food: What you eat can affect your blood sugar levels
Stress: Stress can affect your blood sugar levels
Medications: Some medications can affect your blood sugar levels
Exercise: How much exercise you’ve done can affect your blood sugar levels
Illness: Illness can affect your blood sugar levels
Dehydration: Dehydration can affect your blood sugar levels
Why get tested?
Doctors may perform RBS tests to screen for diabetes and pre-diabetes
RBS tests can also help monitor blood sugar levels in patients who are at high risk
