PHYSICAL EXAMINATION OF URINE

The parameters to be examined on physical examination of urine are listed below. Volume Color Appearance Odor Specific Gravity pH VOLUME Volume of only the 24-hr specimen of urine needs to be measured and reported. The average 24-hr urinary output in adults is 600-2000 ml. The volume varies according to…

TEST FOR DETECTION OF UROBILINOGEN IN URINE

Fresh urine sample should be used because on standing urobilinogen is converted to urobilin, which cannot be detected by routine tests. A timed (2-hour postprandial) sample can also be used for testing urobilinogen. Methods for detection of increased amounts of urobilinogen in urine are Ehrlich’s aldehyde test and reagent strip…

LABORATORY TESTS IN PORPHYRIAS

Porphyrias (from Greek porphura meaning purple pigment; the name is probably derived from purple discoloration of some body fluids during the attack) are a heterogeneous group of rare disorders resulting from disturbance in the heme biosynthetic pathway leading to the abnormal accumulations of red and purple pigments called as porphyrins…

PLATELET GLYCOPROTEIN ANALYSIS

This is done by flow cytometric analysis for detection of lack of GpIb/IX in Bernanrd Soulier syndrome (deficiency of CD42), and lack of GpIIb/IIIa in Glanzmann’s thrombasthenia (deficiency of CD41, CD61).   What is the best protocol for platelet glycoprotein (GPIIb/IIIa) analysis using flow cytometry?   Fresh platelets should always…

TEST FOR D-DIMER

D-dimer is derived from the breakdown of fibrin by plasmin and D-dimer test is used to evaluate fibrin degradation. Blood sample can be either serum or plasma. Latex or polystyrene microparticles coated with monoclonal antibody to D-dimer are mixed with patient’s sample and observed for microparticle agglutination. As the particle…

TEST FOR FIBRINOGEN/FIBRIN DEGRADATION PRODUCTS (FDPs)

FDPs are fragments produced by proteolytic digestion of fibrinogen or fibrin by plasmin. For determination of FDPs, blood is collected in a tube containing thrombin (to remove all fibrinogen by converting it into a clot) and soybean trypsin inhibitor (to inhibit plasmin and thus prevent in vitro breakdown of fibrin).…

ADVANTAGES AND DISADVANTAGES OF AUTOMATED HEMOTOLOGY ANALYZER

AUTOMATED HEMOTOLOGY ANALYZER Automation is a process of replacement of tasks hitherto performed by humans by computerized methods. Until recently, hematological tests were performed only by manual methods. These methods, though still performed in many peripheral laboratories, are laborintensive, and involve use of hemocytometers (counting chambers), centrifuges, Wintrobe tubes, photometers,…
