- Albinism can be diagnosed merely by observation of major or total absence of pigmentation of the skin, hair and eyes. Other tests to diagnose albinism include -. Genetic Testing -. Genetic testing is the most accurate way to diagnose albinism and its specific type.

Gamma-Glutamyl Transpeptidase This test is used to detect diseases of the liver or bile ducts. It is also done along with other tests, such as the ALP test, to tell the difference between liver or bile duct disorders and bone disease. Alkaline phosphatase (ALP) is increased in liver and bile duct disease as well as in bone disease.

Bilirubin A bilirubin test is used to detect an increased level in the blood. It may be used to help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, and blockage of the bile ducts.Bilirubin is an orange-yellow pigment, a waste product primarily produced by the normal breakdown of heme.ilirubin is ultimately processed by the liver to allow its elimination from the body. Any condition that accelerates the breakdown of RBCs or affects the processing and elimination of bilirubin may cause an elevated blood level.

- 1 Type 1 albinism: This form of albinism is characterized by almost no pigmentation and is caused by a defect in a gene for an enzyme * that makes pigment. 2  Type 2 albinism: People with Type 2 albinism usually have some pigmentation; this type is caused by a defect in a gene called the P gene.

Vitamin B12 and Folate Other laboratory tests that may be used to help detect B12 and folate deficiencies include homocysteine and methylmelonic acid (MMA) . Homocysteine and MMA are elevated in B12 deficiency while only homocysteine, and not MMA, is elevated in folate deficiency. low B12 and/or folate level in a person with signs and symptoms indicates that the person has a deficiency but does not necessarily reflect the severity of the anemia or associated neuropathy. Additional tests are usually done to investigate the underlying cause of the deficiency.

Dark Urine?kirk8 Apr 18, 2014 Guide. A bilirubin test measures the amount of bilirubin in a blood sample. Bilirubin is a brownish yellow substance found in bile. It is produced when the liver breaks down old red blood cells. Bilirubin is then removed from the body through the stool (feces) and gives stool its normal color.

- 1 In conditions affecting the liver, damaged liver cells release increased amounts of ALP into the blood. 2  This test is often used to detect blocked bile ducts because ALP is especially high in the edges of cells that join to form bile ducts.n ALP test may be ordered as part of routine laboratory testing, often with a group of other tests called a liver panel. It is also usually ordered along with several other tests when a person has symptoms of a liver or bone disorder.

Bilirubin A bilirubin test is used to detect an increased level in the blood. It may be used to help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, and blockage of the bile ducts.Bilirubin is an orange-yellow pigment, a waste product primarily produced by the normal breakdown of heme.f conjugated (direct) bilirubin is elevated more than unconjugated (indirect) bilirubin, there typically is a problem associated with decreased elimination of bilirubin by the liver cells. Some conditions that may cause this include: 1  Viral hepatitis. 2  Drug reactions.

Coombs test Coombs test (also known as Coombs' test, antiglobulin test or AGT) refers to two clinical blood tests used in immunohematology and immunology. The two Coombs tests are the direct Coombs test (DCT, also known as direct antiglobulin test or DAT), and the indirect Coombs test (also known as indirect antiglobulin test or IAT). The more commonly used test, the Direct Coombs test, is used to test for autoimmune hemolytic anemia.

Rh Incompatibility in Pregnancy: Causes, Symptoms, and Treatment The Test. How is it used? The direct antiglobulin test (DAT), also known as the direct Coombs test, is used primarily to help determine whether the cause of hemolytic anemia, a condition in which red blood cells (RBCs) are destroyed more quickly than they can be replaced, is due to antibodies attached to RBCs.

Thalassemia minor Hgb electrophoresis is performed when a disorder associated with abnormal hemoglobin (hemoglobinopathy) is suspected. The test is used primarily to diagnose diseases involving these abnormal forms of hemoglobin, such as sickle cell anemia and thalassemia.gb A 1 is the major component of hemoglobin in the normal red blood cell. Hgb A 2 is a minor component of normal hemoglobin, comprising approximately 2-3% of the total. Hgb F is the major hemoglobin component in the fetus, but usually exists only in minimal quantities in the normal adult.

What Type of Blood Tests Are Used for Cirrhosis of the Liver? Liver Panel. A liver panel is a group of blood tests that detects problems with liver function, but cannot diagnose a particular disease or condition. Although the specific tests included in a liver panel vary from one laboratory to another, common tests include bilirubin, ALT, AST, ALP, albumin and prothrombin time. The bilirubin test measures the level of waste products from red blood cell breakdown.
