1. Matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) is an accurate method to detect drug-resistant mutations and identify novel mutations in chronic hepatitis B patients treated with lamivudine.
2. MALDI-TOF MS can simultaneously detect multiple mutations in a target sequence and at proportions as low as 10%.
