total lymphocyte count

Abbreviation: TLC
The number of lymphocytes in a specimen of blood. The count may be increased in clonal diseases such as chronic lymphocytic leukemia or decreased in diseases such as AIDS. In AIDS, decreases in the total lymphocyte count usually reflect a marked decline in the number of helper T4 cells.

In the training set, on univariate analysis, the following variables were associated with the presence of HIV co-infection at P<0.1 significance level: increasing age; male gender; lower body-mass index, mid-arm circumference, and triceps skinfold thickness; absence of pulmonary involvement, miliary disease, and cavity formation on chest radiograph; negative sputum-smear and tuberculin skin test status; presence of axillary, inguinal, mediastinal, and intra-abdominal lymphadenopathy, pleural effusion, and meningitis; and low levels of haemoglobin, total lymphocyte count, and serum albumin (Table I).
The CD4+ T-lymphocyte % values were calculated by dividing the absolute CD4+ T-lymphocyte count with the total lymphocyte count and multiplying by hundred.
Initial laboratory values at the referring hospital included the following: leukocyte count 3,300 cells/[mm.sup.3], total lymphocyte count 640 cells/[mm.sup.3], hemoglobin 13 g/dL, and platelet count 400,000 cells/[mm.sup.3].

Laboratory examination of haematological, immunological and biochemical parameters revealed that the patient had a haemoglobin (Hb) of 11.8 g/dl (normal values 10-15 g/dl), erythrocyte sedimentation rate (ESR) of 57 mm (normal value 0-20 mm), total thrombocyte count of 243 x [10.sup.9]/1 (normal values 137367 x [10.sup.9]/1), total leucocyte count of 8.0 x [10.sup.9]/1 (normal values 3.9-9.4 x [10.sup.9]/1), and a high total lymphocyte count (TLC) of 4.1 x [10.sup.9]/1 (normal values 1.2-3.4 x [10.sup.9]/1).
