Fbc normal ranges. Plasma or whole blood. Establish reference ranges fbc variables tend not to follow a normal gaussian distribution gräsbeck. Abnormally high levels of white blood cells may indicate infection tissue damage leukaemia or inflammatory diseases.

There is no need to request a blood film to obtain a differential white count. Full blood count reference ranges. This equates to approximately 27 34 picograms per red blood cell in one litre of blood.

A platelet count that s lower than normal thrombocytopenia or higher than normal thrombocytosis is often a sign of an underlying medical condition or it may be a side effect from medication. In this article all values except the ones listed below denote blood plasma concentration which is approximately 60 100 larger than. It is however important that clinical details are provided to allow the laboratory to decide whether a blood film in addition to the automated analysis is required.

Grossly abnormal fbc results and abnormal blood films will be phoned through to the requestor. 0 15 0 45 g l or 1 of the serum protein concentration glucose. A number of viral infections can cause a temporary reduction in the white cell count.

Normal cell counts do not rule out meningitis or any other pathology. The normal white cell count for adults is 4 0 11 0 x 109 l. These normal ranges provide a guide.

If your platelet count is outside the normal range you ll likely need additional tests to diagnose the cause. 2 8 4 2 mmol l or 60 plasma glucose concentration opening pressure. Red blood cells rbc.

The normal haemoglobin content of red blood cells is 115 150 grams per litre. For paediatric normal ranges please contact laboratory reference ranges for fbc parameters obtained from phase ii of the pathology harmonisation project pathologyharmony co uk. A reference range is usually defined as the set of values 95 percent of the normal population falls within that is 95 prediction interval.

However haemoglobin white blood cell and platelet levels can vary with factors such as age pregnancy and with different hospital laboratories. The normal range for adults is 150 400 x 10 9 l. A picogram is one trillionth of a gram or 1 x 10 12 grams.

It is determined by collecting data from vast numbers of laboratory tests. The frequent lognormal distribution is caused by the fact that values below zero are impossible but high values are possible power transformation is applied to achieve normal distribution.
