alimentary lipemia that occurring after eating.
lipemia retina´lis a milky appearance of the veins and arteries of the retina, occurring when the lipids of the blood exceed 5 per cent and in diabetes mellitus and leukemia.

[lipid + G. haima, blood]

alimentary lipemia  that occurring after ingestion of food.

lipemia

[lipē′mē·ə]
Etymology: Gk, lipos + haima, blood
chylomicrons in plasma causing the plasma to appear cloudy. It occurs following a heavy or fatty meal or may indicate a metabolic lipid disorder.

li·pe·mi·a

(li-pē'mē-ă)
The presence of an abnormally high concentration of lipids in the circulating blood.
Synonym(s): hyperlipidemia, hyperlipoidemia, lipidemia, lipoidemia, lipaemia.

lipemia (liˈ·p·mēˑ·),

n presence of high concentration of lipids in the bloodstream; normally observed after eating.

li·pe·mi·a

Presence of abnormally high concentration of lipids in circulating blood.
Synonym(s): lipaemia.

lipemia

an excess of lipids in the blood; hyperlipemia.

alimentary lipemia
postprandial lipemia (below).
fasting lipemia
that present when food has been withheld for at least 24 hours.
postprandial lipemia
a physiological effect that occurs between 2 and 12 hours after the ingestion of food high in lipids.
lipemia-refrigeration test
refrigeration of a lipemic blood sample may distinguish between triglyceride-rich lipoproteins, which persist in the turbid sample, and chylomicra, which rise to form a flocculent top layer while the sample clears.
lipemia retinalis
that manifested by a milky appearance of the veins and arteries of the retina. Seen in hyperlipoproteinemia in dogs.

Lipemia most often results from specimens collected soon after an individual has had a particularly fatty meal.

Additionally, 78% of LipoClear-treated samples showed lower lipemia indices after treatment than did their paired ultra-centrifuged specimens, suggesting a more-complete removal of interfering lipids.
Less bias occurs with direct LDL-C assays, but again significant background lipemia will affect the assay once TG concentrations exceed 885 mg/dL (10 mmol/L).

Alternative tools found in the LIS would be the cancelled-orders log or a query configured to capture hemolysis, icterus, and lipemia flags from the analyzers.
The hemolysis and icteric indices were not increased above the laboratory's threshold for electrolyte measurement; however, the lipemia index was.
Fibrin clots in serum specimens, hemolysis, and frank lipemia are far more frequent potential interferences in veterinary specimens than may be typically seen in the typical clinical laboratory.
Hemolysis and lipemia can also interfere at high concentrations (2).
These may be seen in patients with cryoproteins, lipemia, high white-blood-cell counts, and giant platelets; and
