What is the normal value in adults of:

Blood pH
7.35-7.45
What is the normal value in adults of:

ALT

What is it used for?
7-55 U/L

The alanine aminotransferase (ALT) blood test is typically used to detect liver injury. It is often ordered in conjunction with aspartate aminotransferase (AST) or as part of a liver panel to screen for and/or help diagnose liver disease. AST and ALT are considered to be two of the most important tests to detect liver injury, although ALT is more specific than AST. Sometimes AST is compared directly to ALT and an AST/ALT ratio is calculated. This ratio may be used to distinguish between different causes of liver damage
What is the normal value in adults of:

AST

What is it used for?
8-48 U/L

The blood test for aspartate aminotransferase (AST) is usually used to detect liver damage. It is often ordered in conjunction with another liver enzyme, alanine aminotransferase (ALT), or as part of a liver panel to screen for and/or help diagnose liver disorders. AST and ALT are considered to be two of the most important tests to detect liver injury, although ALT is more specific than AST. Sometimes AST is compared directly to ALT and an AST/ALT ratio is calculated. This ratio may be used to distinguish between different causes of liver damage.

AST levels are often compared with results of other tests, such as alkaline phosphatase (ALP), total protein, and bilirubin to help determine which form of liver disease is present.
What is the normal value in adults of:

ALP

What is it used for?
45-115 U/L

The alkaline phosphatase test (ALP) is used to help detect liver disease or bone disorders. In conditions affecting the liver, damaged liver cells release increased amounts of ALP into the blood. 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. If one or more of them are obstructed, for example by a tumor, then blood levels of ALP will often be high.

Any condition that affects bone growth or causes increased activity of bone cells can affect ALP levels in the blood. An ALP test may be used, for example, to detect cancers that have spread to the bone or to help diagnose Paget's disease. This test may also sometimes be used to monitor treatment of Paget's disease or other bone conditions, such as vitamin D deficiency.
What is the normal value in adults of:

Albumin

What is the test used for?
3.5-5.0 g/dL

Since albumin is low in many different diseases and disorders, albumin testing is used in a variety of settings to help diagnose disease, to monitor changes in health status with treatment or with disease progression, and as a screen that may indicate the need for other kinds of testing.

An albumin test may be ordered as part of a liver panel to evaluate liver function, along with a creatinine and BUN (Blood Urea Nitrogen) to evaluate kidney function, or along with a prealbumin to evaluate a person's nutritional status.
In adults, what is the normal lab value of:

Total Protein
6.3-7.9 g/dL

Total protein measurements can reflect nutritional status and may be used to screen for and help diagnose kidney disease, liver disease, and many other conditions. Sometimes conditions are first detected with routine testing before symptoms have begun to appear. If total protein is abnormal, further tests must be performed to identify which specific protein is abnormally low or high so that a specific diagnosis can be made.
It is part of the Comprehensive MEtabolic Panel (CMP).
In adults, what is the normal lab value of:

Bilirubin
0.1-1.0 mg/dL

In adults or older children, bilirubin is measured to diagnose and/or monitor liver diseases, such as cirrhosis, hepatitis, or gallstones. Patients with sickle cell disease or other causes of hemolytic anemia may have episodes where excessive RBC destruction takes place, increasing bilirubin levels.
In adults, what is the normal lab value of:

GGT

What is this test used for?
9-48 U/L

Gamma-glutamyl transferase (GGT) levels may be used to determine the cause of an elevated alkaline phosphatase (ALP). Both ALP and GGT are elevated in disease of the bile ducts and in some liver diseases, but only ALP will be elevated in bone disease. If the GGT level is normal in a person with a high ALP, the cause is most likely bone disease. GGT can be used to screen for chronic alcohol abuse (it will be elevated in about 75% of chronic drinkers). Sometimes it may be used to monitor for alcohol use and/or abuse in people who are receiving treatment for alcoholism or alcoholic hepatitis.
In adults, what is the normal lab value of:

LDH

What is this test used for?
122-222 mcmol/L

LDH is as a general indicator of the existence and severity of acute or chronic tissue damage and, sometimes, as a monitor of progressive conditions.
In adults, what is the normal lab value of:

PT

What is this test used for?
8.3-10.8 seconds

Since the Prothrombin time (PT) evaluates the ability of blood to clot properly, it can be used to help diagnose bleeding. When used in this instance, it is often used in conjunction with the PTT to evaluate the function of all coagulation factors. Occasionally, the test may be used to screen patients for any previously undetected bleeding problems prior to surgical procedures.
In adults what is a normal value of:

BUN

What is this test used for?
10-31 mg/dL

The BUN test is primarily used, along with the creatinine test, to evaluate kidney function in a wide range of circumstances, to help diagnose kidney disease, and to monitor patients with acute or chronic kidney dysfunction or failure. It also may be used to evaluate a person’s general health status when ordered as part of a basic metabolic panel (BMP) or comprehensive metabolic panel (CMP).
In adults what is a normal value of:

Creatinine

What is this test used for?
0.8-1.4 mg/dL

The creatinine blood test is used along with a BUN (blood urea nitrogen) test to assess kidney function. Both are frequently ordered as part of a basic or comprehensive metabolic panel (BMP or CMP), groups of tests that are performed to evaluate the function of the body’s major organs. BMP or CMP tests are used to screen healthy people during routine physical exams and to help evaluate acutely or chronically ill patients in the emergency room and/or hospital.
