The decrease of the lentigo fusion gene to 0.01 indicates that the patient’s physical condition has improved. The normal value of the lentivirus fusion gene is generally 0. If a patient finds a steady decline in quantitative gene detection through regular monitoring, he or she can go to a regular testing organization for relevant examinations. It should be noted that even if the value of the gene fusion test is 0, it does not mean that the patient has completely recovered, and there may also be a lack of precision in the instrument, which may result in inaccurate detection. Even if the patient’s condition improves and the treatment effect is good, the patient should still have regular checkups to avoid recurrence of the disease. The use and discontinuation of medication should be in accordance with the doctor’s instructions, and it is not recommended that patients stop or reduce the dosage of medication on their own. At the same time, attention should be paid to the prevention of colds and flu, supplementation of nutrients, improve immunity, eat more easily digested and easily absorbed food, reduce spicy and stimulating food, avoid smoking and alcohol. If discomfort occurs, it is recommended to seek immediate medical attention.
