Reference Value for Cardiac

Cardiac

Creatine phosphokinase (CK) :

Levels rise 4 to 8 hours after an acute MI, peaking at 16 to 30 hours and returning to baseline within 4 days

25-200 U/L

32-150 U/L

CK-MB CK isoenzyme

It begins to increase 6 to 10 hours after an acute MI, peaks in 24 hours, and remains elevated for up to 72 hours.

< 12 IU/L if total CK is <400 IU/L
<3.5% of total CK if total CK is >400 IU/L

(LDH) Lactate dehydrogenase - Total (LDH) will begin to rise 2 to 5 days after an MI; the elevation can last 10 days.

140-280 U/L

SGOT - will begin to rise in 8-12 hours and peak in 18-30 hours

10-42 U/L

Comments

MICROSCOPIC URINALYSIS Methodology A sample of well-mixed urine (usually 10-15 ml) is centrifuged in a test tube at relatively low speed (about 2-3,000 rpm) for 5-10 minutes until a moderately cohesive button is produced at the bottom of the tube. The supernatant is decanted and a volume of 0.2 to 0.5 ml is left inside the tube. The sediment is resuspended in the remaining supernatant by flicking the bottom of the tube several times. A drop of resuspended sediment is poured onto a glass slide and coverslipped.

Liver Enzymes

Liver Enzymes Definition A liver enzyme is a protein that helps to speed up a chemical reaction in the liver. Liver function tests are blood tests that are used to evaluate various functions of the liver - for example, metabolism, storage, filtration and excretion, which are often performed by liver enzymes. However, not all liver function tests are measures of enzyme function. • ALT - (alanine aminotransferase ) - was previously called SGPT is more specific for liver damage. The ALT is an enzyme that is produced in the liver cells (hepatocytes) therefore it is more specific for liver disease than some of the other enzymes. It is generally increased in situations where there is damage to the liver cell membranes. All types of liver inflammation can cause raised ALT. • AST - (aspartate aminotransferase) which was previously called SGOT. This is a mitochondrial enzyme that is also present in heart, muscle, kidney and brain therefore it is less specific
