The measurement or quantification of cells suspended in a fluid phase is performed using flow cytometry. Fluorochrome-coupled antibodies specific for a certain cellular marker are used to label the cells. The fluidics chamber enables that cell travel via a laser…
Specimen collection technique: • Voided urine• Ileal conduit urine• Catheter urine• Bladder washing• Upper urinary tract brush cytology Voided urine • It is the most common sample type• Voided urine undergoes degeneration very quickly hence preservative are used to reduce…
Arbitrarily, the terms karyogram, karyotype and ideogram have often been used. The term karyogram should be applied to a systematic sequence of chromosomes prepared either by drawing, digitizing, or extending photography, indicating that the chromosomes of a single cell will…
Cytogenetics is the study of chromosome morphology, structure, pathology, function, and behavior. Chromosomes are studied by cytogenetic techniques and are best studied at mitotic or meiotic metaphase, although some studies, such as fluorescence in situ hybridization (FISH) methods, may utilize…
Different methods for preparing the cytology smears are available. Nevertheless, these methods work best with different types of specimens. Understanding each procedure can help to determine the right approach for particular cases, eliminating procedures that may yield suboptimal findings and…
