What causes Icteric plasma

Icteric serum is caused by the presence of excess bilirubin in the blood stream as a result of increased production (pre-hepatic) or inappropriate excretion (hepatic and post-hepatic).

What does it mean when a blood sample is Icteric?

Icterus, also known as jaundice, is used to describe the yellowish-greenish color observed in the sclera of the eyes or in plasma/serum samples of patients with very high concentrations of bilirubin.

What does a high icterus index mean?

Medical Definition of icterus index : a figure representing the amount of bilirubin in the blood as determined by comparing the color of a sample of test serum with a set of color standards an icterus index of 15 or above indicates active jaundice.

What is the clinical significance of the icterus index?

Icteric index. The number reported under icterus is an estimation of the total bilirubin concentration in mg/dL rounded to the nearest whole number. The icterus index can be used to determine if there is hyperbilirubinemia, i.e. if the total bilirubin is increased, the icteric index should closely match the value seen.

What color is Icteric plasma?

Icteric serum or plasma varies in color from dark to bright yellow, rather than the normal straw color.

What causes icterus?

The most common causes include gallstones and malignancy, such as pancreatic cancer and cholangiocarcinoma. In adults, scleral icterus can also occur due to liver dysfunction. Causes include drug-induced liver disease, parasites (liver fluke), viral hepatitis, and alcoholic and non-alcoholic cirrhosis.

Is Icteric normal?

Icterus (or the icterus index) is a measure of the yellow colour of serum. This colour is normally due almost exclusively to the presence of bilirubin, a hemoglobin waste product from the red blood cells. The icterus index is expressed as a number of “plus” signs (from zero to ++++). An icterus index of zero is normal.

What is the difference between icterus and jaundice?

What is icterus? Icterus is also known as jaundice or yellow jaundice. It refers to an excessive accumulation of a yellow pigment in the blood and tissues. When icterus has been present for any length of time, it will discolor many tissues and will become visible as jaundice on most body surfaces, including the skin.

What causes specimen hemolysis?

Hemolysis resulting from phlebotomy may be caused by incorrect needle size, improper tube mixing, incorrect filling of tubes, excessive suction, prolonged tourniquet, and difficult collection.

How does icterus affect CBC results?

Icterus has minimal to no effect on hematologic results, including plasma protein measured by refractometry (Gupta & Stockham 2014).

Article first time published on

Which chemistry analytes are most affected by hemolysis?

Two analytes greatly impacted by hemolysis are potassium and lactate dehydrogenase, in which their concentrations in erythrocytes are more than 20 times and 150 times higher than it is in serum, respectively.

Why is my plasma dark yellow?

The reason plasma is typically yellow in colour and not red like our blood is due to a pigment called bilirubin. … It is circulated in your blood then travels to your liver where it is processed and eventually removed. Higher bilirubin values cause a stronger yellow blood plasma colour.

Why does birth control turn your plasma green?

Ceruloplasmin is a plasma glycoprotein (α2-globulin), which acts as a copper carrier and as an acute-phase reactant. Tovey and Lathe reported green plasma in young women on contraceptive pills and confirmed elevated ceruloplasmin levels in the green plasma units by immunodiffusion and oxidase method in their study.

What is Icteric hepatitis?

Icteric hepatitis is associated with a prodromal period, during which a serum sickness –like syndrome can occur. The symptomatology is more constitutional and includes the following: Anorexia. Nausea. Vomiting.

What tests are affected by icterus?

IncreasedDecreasedPotassium (K+)Troponin TLactate Dehydrogenase (LDH)HaptoglobinSGOT/ASTBilirubinSGPT/ALTAmylase

What level of bilirubin causes icterus?

The normal serum levels of bilirubin are less than 1 milligram per deciliter (mg/dL). However, the clinical presentation of jaundice with peripheral yellowing of the eye sclera, also called scleral icterus, is best appreciated when serum bilirubin levels exceed 3 mg/dl.

What does icterus mean?

Definition of icterus medical. : yellowish pigmentation of the skin, tissues, and body fluids caused by the deposition of bile pigments : jaundice The patient appeared very lethargic and mildly dehydrated with severe icterus.— Antonio Giuliano et al.

When does kernicterus occur?

In most cases, the syndrome characteristic of kernicterus develops by three to four years of age.

What causes yellow skin?

Yellow skin is most commonly caused by a condition called jaundice, which occurs when there is a high level of bilirubin in the blood. Bilirubin is a yellowish compound that is formed when old or damaged red blood cells break down.

What are the 3 main veins to draw blood?

3.05. The most site for venipuncture is the antecubital fossa located in the anterior elbow at the fold. This area houses three veins: the cephalic, median cubital, and basilic veins (Figure 1).

What does slightly Hemolyzed specimen mean?

The term hemolysis designates the pathological process of breakdown of red blood cells in blood, which is typically accompanied by varying degrees of red tinge in serum or plasma once the whole blood specimen has been centrifuged.

Why is haptoglobin low in hemolytic anemia?

Because the free hemoglobin is not released into the blood, the haptoglobin is not used up and remains at a normal level. However, in severe extravascular hemolysis, haptoglobin level can be low because excess hemolysis can release some free hemoglobin into circulation.

What causes obstructive jaundice?

Obstructive jaundice may be due to a number of causes, all of which narrow or block the bile ducts in some way: Gallstones. Pancreatic cancer, when it occurs near the tube connecting the pancreas to the intestines. Swelling of lymph glands near the bile duct.

How is Carotenemia different from jaundice?

Carotenemia is a harmless condition in which the skin turns a yellowish color from eating lots of certain foods. Unlike jaundice, the whites of the eyes remain white. This happens most often between 6 and 18 months of age.

What does mild hepatomegaly mean?

An enlarged liver is one that’s bigger than normal. The medical term is hepatomegaly (hep-uh-toe-MEG-uh-le). Rather than a disease, an enlarged liver is a sign of an underlying problem, such as liver disease, congestive heart failure or cancer. Treatment involves identifying and controlling the cause of the condition.

What causes falsely elevated hemoglobin?

Medical conditions that can cause high hemoglobin levels include: Polycythemia vera (the bone marrow produces too many red blood cells) Lung diseases such as COPD, emphysema or pulmonary fibrosis (lung tissue becomes scarred) Heart disease, especially congenital heart disease (the baby is born with it)

How do you avoid lipemic samples?

If it is possible, in order to avoid lipemia, the sample has to be taken at least 5–6 hours after administration of Intralipid (19).

What other factors of specimen collection can have an adverse effect on chemistry analytes?

• Time before separation from cells (for plasma). …
• Centrifugation conditions. …
• Special separation requirements. …
• Division of the sample into a sufficient number of aliquots of a sufficient volume. …
• Temperature and time between separation and analysis.

Does hemolysis affect AST and ALT?

Hemolysis may falsely increase the following analytes: AST, alanine transaminase (ALT), LDH, total bilirubin, glucose, calcium, phosphorus, total protein, albumin, magnesium, amylase, lipase, creatine kinase (CK), iron, hemoglobin, and mean corpuscular hemoglobin concentration (MCHC).

Does hemolysis affect LDH?

Hemolysis may also lead to elevated LDH and bilirubin. LDH is present in red cells and hemolysis causes release into the plasma.

What labs are affected by hemolysis?

Certain lab tests can be affected and the reported results will be inaccurate. It falsely decreases values such as RBC’s, HCT, and aPTT. It can also falsely elevate potassium, ammonia, magnesium, phosphorus, AST, ALT, LDH and PT.
