BII-phobics may be given pictures of needles or blood, asked to illustrate needles or scenes with blood, or to speak about their phobic triggers. This systematically progresses to the point of the individual directly confronting a phobic stimulus: being given a needle, witnessing blood being drawn, etc. As exposure continues, it is expected that the phobic response will become less pronounced, and symptoms less debilitating.While AT targets the phobia’s physiological response, aiming to raise blood pressure and directly prevent fainting, AR focuses mainly on helping an individual avoid the phobia’s associated anxiety. A phobic will learn progressive relaxation techniques to help to calm themselves upon exposure to a trigger. Temporary alleviation of symptoms
Drinking water before a triggering experience such as blood donation has been indicated to aid in prevention of a fainting response. Water will increase sympathetic nervous system activation, raising blood pressure and combating vasovagal response.Certain physical maneuvers also have the capacity to temporarily boost blood pressure, alleviating symptoms of pre-syncope like lightheadedness by boosting blood flow to the brain. These include the phobic individual crossing their legs, making tight fists with both hands, or engaging muscles of the trunk or arms. Coughing, which can similarly increase cranial blood flow, can also be useful as a coping mechanism to avoid pre-syncope and syncope.Symptoms of a phobic response are generally able to be fully alleviated within a few minutes simply by removing the phobic trigger.
Lymphocytosis is an increase in the number or proportion of lymphocytes in the blood. Absolute lymphocytosis is the condition where there is an increase in the lymphocyte count beyond the normal range while relative lymphocytosis refers to the condition where the proportion of lymphocytes relative to white blood cell count is above the normal range. In adults, absolute lymphocytosis is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 109/L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds 40%, it is recognized as relative lymphocytosis. Causes
Lymphocytosis is a feature of infection, particularly in children. In the elderly, lymphoproliferative disorders, including chronic lymphocytic leukemia and lymphomas, often present with lymphadenopathy and a lymphocytosis.Causes of absolute lymphocytosis include:

acute viral infections, such as infectious mononucleosis (glandular fever), hepatitis and Cytomegalovirus infection
other acute infections such as pertussis
some protozoal infections, such as toxoplasmosis and American trypanosomiasis (Chagas disease)
chronic intracellular bacterial infections such as tuberculosis or brucellosis
chronic lymphocytic leukemia
acute lymphoblastic leukemia
lymphoma
post-splenectomy state
CARD11-related congenital B cell lymphocytosis (rare, also known as BENTA disease)Causes of relative lymphocytosis include:

age less than 2 years;
acute viral infections;
connective tissue diseases,
thyrotoxicosis,
Addisons disease,
splenomegaly with splenic sequestration of granulocytes. Diagnosis
Lymphocytosis is usually detected when a complete blood count is obtained. If not provided the lymphocyte count can be calculated by multiplying the total white blood cell (WBC) count by the percentage of lymphocytes found in the differential count.
