The reagents consist of potassium phosphate, sodium dithionite, and saponin. A Sickle Turbidity Tube Test involves the addition of dithionite to a blood sample. If you find our videos helpful you can support us by buying something from amazon. False-positive solubility test for sickling may be due to polycythemic blood; interference by some forms of hyperglobulinemia; and a variety of abnormal hemoglobins, including I, Bart, C Georgetown, Alexandra, C Harlem, Porto Alegre, Memphis/S, C Ziguinchor, and S Travis. Sodium dithionite EMPLURA ® Synonym: Sodium dithionite, Sodium hydrosulfite, Sodium hypodisulfite CAS Number 7775-14-6. EC Index Number 231-890-0 solubility test: a screening test for sickle cell hemoglobin (Hb S), which is reduced by dithionite and is insoluble in concentrated inorganic buffer; addition of blood showing Hb S to buffer and dithionite causes opacity of the solution. The crystal refract and deflect light ray, as such yield a turbid solution. Sickle Cell Screening Test: Sodium Dithionite (Solubility Test) Most commonly used screening test for Hemoglobin S Based on the relative insolubility of hemoglobin S when combined with a reducing agent (sodium dithionite) Concerns Solubility Test. SICKLEDEX Solubility Buffer is a 2.3 M potassium phosphate buffer solution. Molecular Weight 174.11 . Sodium dithionite has a water solubility of 18.61 g/100 mL solution (approximately 186.1 g/L) at 20.0 °C. Sodium dithionite is a combustible solid which slowly decomposes when in contact with water or water vapor, forming thiosulfates and bisulfites. An inexpensive, rapid, convenient screening tube test for the detection of hemoglobin S and non-S sickling hemoglobins has been developed, which has a molecular basis. Refer to SDS. Itano andPauling introduced (9)theuseof sodium dithionite inphosphate-buffered solutions ... Alldithionite tube test specimens read as positive (Figure 1)may beduetobothhemo-globin Sandnon-Ssickling hemoglobins (4). With this process allowed solubility test to be carried out.Reagent for Hb S solubility TestThe test for Hb Solubility test solubility test A screening test for sickle cell haemoglobin ( hb S ), which is reduced by dithionite and is insoluble in concentrated inorganic buffer ; addition of blood showing hb S to buffer and dithionite causes opacity of the solution . For In Vitro Diagnostic Use. solubility test(7,8),butstillnodisclosures or specifications areforthcoming. SICKLEDEX Reagent Powder vials contain Saponin and Sodium Hydrosulfite. This reaction evolves heat, which can further accelerate the reaction or cause surrounding materials to burn. sickle Cell DiseaseWith High concentration of phosphate buffer, it give hemoglobin S (Hb S) insoluble in the reduce state.When in the buffer, it form a shape like water crystal. 2. The preservative is 0.1% 2-chloroacetamide. Empirical Formula (Hill Notation) Na 2 O 4 S 2. PRECAUTIONS 1. MDL number MFCD00011640. Warning: Sodium Hydrosulfite is a flammable solid and strong reducing agent. Does not differentiate between hemoglobin S If the mixture becomes cloudy, Hb S is likely present; Another type of sickle test involves the use of metabisulfite. A positive reaction also occurs in the presence of … One method specifies hemoglobin electrophoresis as the initial screening technique, followed by a solubility (dithionite) test when a (nonspecific) "S band" is noted. 1 Positive tests should be confirmed by hemoglobin fractionation.
