what is the chemical reagent used to dilute samples of blood?
812946
Chemical reagents are not used to dilute blood. Depending on the test needed, some have a non clotting agent put in. Others let it clot and take off the serum to test for various reasons. What you are probably referring to is an agent to either stop clotting or preserve the specimen.

Complete blood count with manual differential (smearing the blood on a glass slide, staining it and doing the differential, or categorizing the white blood cells by looking at them.  Comprehensive metabolic would probably be what we would call a full chem panel, with electrolytes, and enzymes testing a variety of biochemical systems in your body.

it's luminol i'm 100 % sure.Luminol is used by crime scene investigators to locate occult blood, even if it has been cleaned or removed.Using its natural property of chemiluminescence, it luminesces upon reacting with hydrogen peroxide. Iron in hemoglobin, a pigment present in blood, is provided as a catalyst in the luminescence. The glow lasts for about 30 seconds and is blue. Detecting the glow requires a fairly dark room. Any glow detected is documented by a long exposure photograph.

Benedict's reagent (also called Benedict's solution or Benedict's test) is a reagent used as a test for the presence of reducing sugars (such as glucose, lactose, and fructose, but not sucrose), or more generally for the presence of aldehydes, in a solution.\n\nBenedict's reagent contains blue copper(II) sulfate (CuSO4) · 5H2O which is reduced to red copper(I) oxide by aldehydes, thus oxidizing the aldehydes to carboxylic acids. The copper oxide is insoluble in water and so precipitates. The colour of the final solution ranges from green to brick red depending on how many of the copper(II) ions are present. Benedict's test cannot be used to detect the presence of aromatic aldehydes.\n\nWhen Benedict's is used as a chemical test for the presence of reducing sugars in food, the food sample is dissolved in water and about 5ml of the sample solution is added to 5ml of Benedict's qualitative reagent. The mixture is placed in a boiling waterbath for 5 minutes and any precipitate formed is recorded as a positive for the presence of sugar in the food.\n\nThe reason sucrose has a negative result in Benedict's solution is because sucrose is a non-reducing sugar when in contact of a base. Benedict’s solution cannot break down the bonds of sucrose like other sugars, this would be the opposite if it were an acid.\n\nBenedict's reagent can be used to test for the presence of glucose in urine. Glucose found to be present in urine is an indication of diabetes. 5.0ml of Benedict's qualitative solution is mixed with 0.5ml of urine and the mixture is put in a boiling water bath for 5 minutes. The results are recorded thus:\n\nno precipitate           -\nGreen                    a trace\nyellow                   +\norange                   ++\nred                      +++\nOnce sugar is detected in urine, further tests have to be undergone in order to ascertain which sugar is present. Only glucose is indicative of diabetes.\n\nBenedict's quantitative reagent is used to determine how much sugar is present. This solution forms as white precipitate rather than a red one and so can be used in a titration as follows:\n\nAccurately measure 25ml of Benedict's quantitative reagent and pour into a 100ml conical flask. \nAdd 6g of anhydrous sodium carbonate, to keep the solution alkaline. \nAdd a few anti-bumping granules and bring the solution to a gentle simmer. \nPour the sample into a burette and allow the sample to run from the burette into the conical flask until all the blue colour has disappeared. \nRepeat twice more, but this time allow the bulk of the sample to run into the conical flask all at once; then when the end point is near let it drip in one drop at a time, and boil for 30 seconds between each addition. \nAverage the results. \nThe titration should be repeated with 1% glucose solution instead of the sample in order to calibrate the Benedict's.\n\nThe concentration of glucose in the sample can be worked out by comparing the volume needed to discolour the Benedict's with the volume of 1% glucose solution that is needed to discolour the Benedict's.\n\n\n\n\nBenedict's reagent is named after an American chemist, Stanley Rossiter Benedict (1884 – 1936). It is now often used in place of Fehling's solution.

i dont know what u mean by the second question but for blood, i just make a tiny circle and make it red so it looks like blood.

1) Generally soap and water is enough to dissolve blood and wash it away. If you have blood on you, you will also want a disinfectant, such as bleach, hydrogen peroxide, or the alcohol found in water-free hand rinse.\n2. The x-ray machines in airports are much more powerful. X-rays are inherently harmful to humans, so the dosage used in hospitals are much lower than those used in airports.\n3. Probably none. Likely, neither would anyone's bed sheets. Remember that what is found is often a residue, a protein, after washing the sheets in bleach.

It depends on what chemicals you need. Sigma-Aldrich corp. is a common supplier of a variety of chemicals for scientific research, and it has numerous representatives in Europe. However, research-grade chemicals are quite expensive; maybe for a school project you can find lower purity and cheaper reagents. You should ask your school chemistry teacher about that.

EDTA has very little selectivity so I doubt you will find much more.Masking/demasking agents such as cyanide complexes,phosphate anions.. are nothing else than complexation examples.Another method is called kinetic masking; for example determination of Cr and Fe in steel sample solution (under cool condition,the EDTA will react with Fe first and after you heat the solution the EDTA will react with Cr).The choice of indicator might increase selectivity (different indicators have different reaction rate)but I'm not sure about that one...

Use hydrogen peroxide. It will bubble the blood out. Soak it then rinse it. Blot it dry lightly then repeat til the stain is mostly gone then wash it in cold water with regular detergent.

The is no specific wet test that would involve reagents that you would be able to get.  They are pretty exotic reagents.  Much cheaper would be to take a sample to a local lab and pay $25 or so for a copper test.\n\nIf there are no other metals believed present, you can do this.  Take the solution or solids and acidify until dissolved. Filter any solids left and decant.  Add ammonium hydroxide (15M) to the decant until the solution is slightly basic.  If the solution is not blue, copper is not present in more than trace levels.  If it is blue, add acetic acid (5M) dropwise until the blue color just disappears.  Then add 2 drops of 0.2M K4Fe(CN)6.  The formation of a red solid confirms the presence of copper.  Note this only works if copper is the only metal above impurity levels.\n\nTo see if chloride is present gets very complicated by wet methods.

If your serious your answer is... To dilute water you must use Heavy water,  Often referred to as Atomic water. Which is water with molecules removed   Oh dont forget the magic dust

No research is going on very fast. At laboratory stages artificial blood is already formed.Soon we will synthesize it in yhe lab.Blood substitutes are used to fill fluid volume and/or carry oxygen and other gases in the cardiovascular system. Although commonly used, the term is not accurate since human blood performs many important functions. Red blood cells transport oxygen, white blood cells defend against disease, platelets promote clotting, and plasma proteins provide various functions. The preferred and more accurate terms are volume expanders for inert products, and oxygen therapeutics for oxygen-carrying products. Examples of these two "blood substitute" categories:\nVolume expanders: inert and merely increase blood volume. These may be crystalloid-based (Ringer's lactate, normal saline, D5W (dextrose 5% in water)) or colloid-based (Haemaccel, Gelofusin). \nOxygen therapeutics: mimic human blood's oxygen transport ability. Examples: Hemopure, Oxygent, PolyHeme. \nOxygen therapeutics are in turn broken into two categories based on transport mechanism: perfluorocarbon based, and hemoglobin based.\nVolume expanders are widely available and are used in both hospitals and first reponse situations by paramedics and emergency medical technicians. Oxygen therapeutics are in clinical trials in the U.S. and Europe, however Hemopure is more widely available in South Africa.

I don't think so; you need a blood sample to test its sugar content.\n\nThere are some new testers that use very little blood, but they still use a sample.

I'd say probes.  They cut down on cost.  If you have to supply a new tip each time reagent is dispensed, that cost can add up fast.  If your talking samples, then, well, I'd have to go with probe again - as long as it gets a good was between samples to cut down on carry over.
