Comparison of Glucose Values of Blood Samples Taken in Three Different Ways

The purpose of the study was to determine differences and correlations between the blood glucose values of venous blood and the first and second drops of capillary blood samples taken in three different ways. Blood samples were (a) venous blood, (b) the first and second drops of capillary blood from the middle finger of the right hand (only washed with soap and water), and (c) the first and second drops of capillary blood from the middle finger of the left hand (washed with soap and water and cleaned with alcohol). It was concluded that the fasting capillary blood glucose values could be used in place of venous blood glucose values, that only washing the hands with neutral soap and water for 30 s could be sufficient for capillary blood glucose measurement, and that the first or second blood drop from a clean hand could be used for capillary blood glucose measurement.

New Evidence

This analytical comment discusses what standards are needed for the evaluation of the accuracy of glucose measurement systems continuously measuring glucose in the interstitial fluid. Since accuracy standards for continuous glucose monitoring (CGM)/flash glucose monitoring (FGM) systems are currently based on modeling studies or consensus of experts, we raised the question whether non-inferiority trials evaluating the safety and efficacy of CGM/FGM measurements compared to capillary blood glucose measurement with point-of-care devices could help to establish clarity about the needed accuracy standards of CGM/FGM. Such trials could also support the replacement of capillary blood glucose measurements by modern CGM/FGM systems.

The purpose of this study is to compare whether or not there is a difference between venous and capillary blood samples in blood glucose measurements and investigate the effects of different aseptic methods used in skin cleaning before collecting blood samples on measurement results. This quasi-experimental study was conducted with 109 patients. The capillary first and second blood drop values taken from the patients after fasting and at 2 hours following 75 g oral glucose tolerance test (OGTT) and capillary and venous blood glucose values were compared. There was no significant difference between the median venous blood glucose value and the capillary second blood drop value taken after wiping the finger with alcohol. There was no significant difference between the first and second blood drop values of capillary blood glucose 2 hours after OGTT.

The ‘Dextrostix’-reflectance meter system for blood glucose analysis has been evaluated using a blood glucose reference method. A high degree of concordance between the two methods was obtained when analyses were performed by skilled laboratory staff on venous blood samples containing fluoride, with a 75 s contact time. Skilled laboratory staff performed significantly better than unskilled staff. Capillary blood glucose concentrations correlated poorly with concentrations in venous blood samples taken at the same time as the capillary blood.

The Impact ◽

Sweet Almond

The reliability of capillary blood glucose measurements is tremendously important for patients’ care and follow-up. Some factors independent of glucose control could however affect readings during ambulatory monitoring of capillary glucose levels in patients with diabetes mellitus. We sought to evaluate the impact of three body lotions commonly used in Cameroon on different strata of glycaemia. We explored their influence over time on measured capillary glucose values. We enrolled 16 participants. Eligible individuals were adult patients with diabetes (n=12) stratified into three levels of capillary glucose values (100 ± 40 mg/dL [5.55 ± 2.22 mmol/L], 200 ± 40 mg/dL [11.1 ± 2.22 mmol/L] and 300 ± 40 mg/dL [16.65 ± 2.22 mmol/L]) and normoglycaemic individuals (n=4). We measured capillary blood glucose before application, immediately after, then 5, 30 and 60 minutes after application of sweet almond oil, corticosteroid cream and hydroquinone lotion. The measurements made on impregnated body lotion-permeated fingers were compared to that of a clean finger. We observed a significant increase (delta [95% confidence interval, CI]: 119.5% [77.4–222.1]) of capillary glucose level immediately after administration of hydroquinone-containing body lotion (p<0.001). Capillary glucose values after the use of corticoid cream and sweet almond oil was stable 5, 30 and 60 minutes after application (p=0.875 and p=0.883 respectively). In the case of the hydroquinone-containing body lotion, there was a significant difference between capillary glucose level at 5 minutes (delta [95%CI]: 81.6% [55.3–214.2]; p<0.001), 30 minutes (delta [95%CI]: 71.6% [21.8–134.6]; p<0.001) and 60 minutes (delta [95%CI]: 58.3% [2.8–133.3]; p=0.013) after application compared to the value obtained from the clean finger. We observed from our study that there were significant variations in capillary blood glucose measurements induced by the use of hydroquinone lotion.

A comparison has been made between three methods for measuring capillary blood glucose collected on filter paper, including a new method using a Beckman glucose analyser 2. The methods are suitable for use with capillary blood spots collected onto filter paper for monitoring the control of diabetic patients. Their accuracy, precision, and recovery of glucose were similar. Glucose measurement with the Beckman glucose analyser 2 involves elution of the dried blood spots with 2% trichloroacetic acid and injection of a fraction of the eluate into the analyser. The method provides a simple and rapid alternative procedure for laboratories that do not have a heavy workload for this type of assay.

Precise Quantification

Diabetes mellitus is one of the most spreading diseases prevalent in the world. The Diabetic patients where in desideratum of monitoring their blood glucose level conventionally for a certain periodic of time. If they were nescient of their checkup it may lead to sundry symptoms like the feel profoundly slothful, tired etc. So they require for a periodic check up without fail. In clinic the prefer syringes for amassing the samples,in some worst cases there will be a possibility of unhydrated syringes . For checking they were in desideratum of a modicum of blood samples. For a precise quantification they will integrate some chemical substance to detect the value. While taking blood samples they feel so uncomfortable, pain and if the syringes where already used are not felicitously sterilized it may lead to sundry disease. The another method for quantifying the sample is a non-invasive. In non-invasive method there will be no desideratum of any syringe. It will be pain less and withal comfortable for the patients. In this paper we are introducing a non-invasive method in lieu of invasive method to be liberate from pain. Our proposed system consists of near infrared transmitter and receiver , a light dependent resistor etc,. The rays are sanctioned to passes through the finger it will quantify the glucose present in our cell and the output is given to the processor. The processed output will determine the quantity of glucose present in the blood . Then determinately the obtained output will be exhibited in the Liquid Crystal Exhibit.
