Plasma and serum are two major components of the blood and the circulatory system. Earlier blood glucose was measured in whole blood.

The serum is used in diagnosing the cholesterol proteins sugar level etc present in the blood.
Difference between serum and plasma glucose. Both can be extracted by centrifugation. Hence serum may be used for blood glucose determination with an error of 115. The difference is that plasma numbers read about 10 - 12 higher than the older whole blood numbers.
Glucose can be measured in whole blood or serum ie plasma. Plasma contains 95 water content whereas serum contains 90 water content. Any difference is an artifact due to sample handling.
Plasma is the watery part of the blood without cells while serum is the plasma without the clotting factors. 1 Levels are higher in the arterial blood because some of the glucose diffuses from the plasma to interstitial fluid IF as blood circulates through the capillary system. If you have elevated plasma glucose then you should speak with your.
Therefore plasma glucose and blood glucose are both measuring the amount of blood circulating in your bloodstream. Hence serum may be used for blood glucose determination with an error of 115. This further evidence of the difference between IG and BG should be considered when interpreting glucose measurements from devices that sample interstitial fluid.
18 rows Plasma is a clear and yellowish fluid part of the blood. On storing the sample at room temperature for 8 hr the serum glucose value decreased by 8. The animal serum is used as anti-toxins anti-venom and for vaccinations.
Specifically delay in separating serum or plasma. The mean difference between the glucose concentrations determined by the biochemical analyzer and the POCG in serum plasma and whole blood was 04 03 and 31 mgdL respectively for canine samples and 7 6 and 32 mgdL respectively for feline samples. Although this difference was statistically significant it may not be physiologically relevant.
Plasma contains fibrinogens whereas serum lacks fibrinogens. The glucose concentration of venous plasma and venous serum should theoretically be the same. Serum gave values lower than fluoride plasma by 115.
Plasma is a component of blood--it includes the non-cellular part of blood. Whereas plasma is the liquid that remains when anticoagulant is added to prevent clotting. OBJECTIVE This study investigated whether glucose readings from a sensor sampling in interstitial fluid differ substantially from blood glucose BG values measured at the same time.
Nonetheless measurement of glucose in serum is not recommended for the diagnosis of diabetes 6 7 while plasma allows samples to be centrifuged promptly without waiting for the blood. Plasma helps in regulation of body temperature and maintenance of blood pressure. On storing the sample at room temperature for 8 hr the serum glucose value decreased by 8.
Nowadays serum is extracted from blood and glucose is measured in the serum. Plasma separation is easy and inexpensive whereas serum separation requires expertise and time. This is the key difference between plasma and serum.
Serum gave values lower than fluoride plasma by 115. Although this difference was statistically significant it may not be physiologically relevant. So if your fasting and pre-meal blood glucose target is 90 - 130 mgdl plasma glucose it would be 80 - 120 mgdl if your meter reads whole blood.
However there is striking difference between plasma and serum. There is some discussion of this in the following paper looking at technical challenges for glucose tester makers. Serum is the liquid that remains after the clotting of blood.
Plasma has a higher water content than whole blood so there is more dissolved glucose in plasma compared with whole blood and readings are 15 to 20 percent higher. Serum and plasma are obtained from the liquid portion of the blood that is obtained when the cells are removed. There is a 35 mgmL difference between arterial and venous levels with higher differences in the postprandial state.
Conclusions and clinical relevance. New blood glucose meters for home use now report blood glucose only in terms of plasma glucose. Technically the difference is that plasma contains more glucose as it has a higher water content and therefore more dissolved glucose.
Both plasma and serum. With regards to the differences in blood glucose level between plasma and serum some studies reported that plasma glucose is higher than serum glucose whereas other studies found no difference. Anti-coagulants are required to separate plasma whereas anti-coagulants are not required to obtain the serum.
