What is analysed?
Methotrexate analysis involves measuring the levels of methotrexate in the blood to monitor drug levels and assess treatment efficacy.
What does the result mean?
The result indicates the concentration of methotrexate in the bloodstream. It helps assess whether the drug levels are within the therapeutic range and if the treatment is effective.
Why undergo the analysis?
Methotrexate analysis is conducted to ensure therapeutic drug levels, prevent toxicity, and evaluate treatment response in conditions such as rheumatoid arthritis, psoriasis, and certain cancers.
When to undergo the analysis?
Methotrexate analysis is typically performed at specific intervals during treatment to monitor drug levels and adjust dosages as needed.
What sample is required?
A blood sample is required for methotrexate analysis.
Is any prior preparation necessary?
No specific preparation is usually necessary before methotrexate analysis. Patients should follow their healthcare provider's instructions regarding medication timing and fasting requirements.
How is it used?
Methotrexate levels guide healthcare professionals in optimising therapy, ensuring adequate disease control, and minimising the risk of toxicity.
What are the normal values?
Normal methotrexate levels vary depending on the specific treatment regimen, patient's medical condition, and treatment goals. Therapeutic ranges are established based on individual patient characteristics and disease severity.

This table provides a general overview of methotrexate levels and their interpretation, aiding healthcare professionals in managing methotrexate therapy effectively.
What do altered values signify?
Altered methotrexate levels may indicate subtherapeutic or toxic drug concentrations. Low levels may lead to inadequate disease control, while high levels may increase the risk of toxicity and adverse effects.
