On-chip counting the number and the percentage of CD4+ T lymphocytes
Lab Chip, 2008A novel technique is reported for counting the number and the percentage of CD4+ T lymphocytes in a polydimethylsiloxane (PDMS) microchannel. This system integrates optical fluorescence detection with resistive pulse sensing enhanced by a metal oxide semiconductor field effect transistor (MOSFET).

Evaluation of a manual CD4+ count kit for determination of absolute CD4+ T-lymphocyte counts.
Journal of the Medical Association of Thailand = Chotmaihet thangphaet, 2008The aim of the present study was to evaluate a manual CD4+ count kit assay (CD4+: cytospheres) for CD4+ T-lymphocyte count compared with flow cytometric method in HIV infected patients.One hundred thirty three HIV infected patients were recruited from the out patient department of Khon Kaen Hospital.

Bet 2: Estimating CD4+ counts from the absolute lymphocyte count in the ED
Emergency Medicine Journal, 2018A 37-year-old patient who has never been to your hospital presents for shortness of breath. He reports a history of HIV but is not currently on treatment and does not know his last CD4+ count. His oxygen saturation is 94% on room air, and lung sounds are distant.

Protracted cutaneous disorders in association with low CD4+ lymphocyte counts
British Journal of Dermatology, 1995We report two patients with skin disorders usually associated with severe immunosuppression, who had low CD4+ lymphocyte counts but normal immunoglobulin levels. The patients were HIV negative, and had CD4+ lymphocyte counts just above 300/mm3, but they presented with cutaneous manifestations of profound immunodeficiency.

A STUDY ON TOTAL LYMPHOCYTE COUNT AND CD4 COUNT IN HIV AFFECTED PATIENTS
International Journal of Biological Studies, 2022Purpose: The study aimed to assess the total lymphocyte count and CD4 count in HIV affected patients. Methodology: The approach we used in this study was to gather and analyze a wide range of research articles. Findings: Worldwide estimates of people living with Human Immunodeficiency Virus was approximately 32 million in 2007 with ...

A PDMS-based disposable microfluidic sensor for CD4+ lymphocyte counting
Biomedical Microdevices, 2008A refined sensor for CD4+ lymphocyte count was developed and evaluated by comparison to flow cytometry. The micropillar structured sensor surface was cast in PDMS polymer and surface modified to gain biocompatibility and CD4-cell capturing properties. The sensor works by pure capillary action and sample filling and rinsing is performed without external

AIDS, 2004
Although the depletion of CD4 T cells remains the most reliable marker for estimating the degree of immunosuppression in HIV-1-infected individuals several authors have investigated the possible prognostic and predictive role offered by total lymphocyte count (TLC) as a surrogate of the CD4 cell count in resource-limited settings (RLS).

Journal of Acquired Immune Deficiency Syndromes and Human Retrovirology, 1996
In South Africa researchers compared the concurrent total lymphocyte counts (TLCs) and CD4+ T cell counts of 128 HIV positive patients with pulmonary tuberculosis (TB) with those of 703 HIV positive patients without TB to determine the practicality of TLCs as a marker of severe immunosuppression in patients with HIV and TB.

Modelling Progression of CD4-Lymphocyte Count and Its Relationship to Survival Time
Biometrics, 1994The purpose of this article is to model the progression of CD4-lymphocyte count and the relationship between different features of this progression and survival time. The complicating factors in this analysis are that the CD4-lymphocyte count is observed only at certain fixed times and with a high degree of measurement error, and that the length of the
