The glucose level in Pseudohypoglycemia

Pseudohypoglycemia is used to describe relieving of siphons (e.g. mental sulfur, disorientation, confusion, vibration), after eating, in individuals with personalities and psychological conditions. The values of plasma glucose in all those patients are within the range of the references Pseudohypoglycemia is an event in the case of a person with a plasma glucose concentration above 70 mg/dl (>3.7 mmol/L) with typical symptoms of hypoglycemia. In the past, the phrase was used to characterize the variance in actual plasma/capillary glucose measurements.

If your blood sugar (glucose) levels aren’t clinically low, but you still feel weak, sweaty, dizzy, and generally unwell, you may be experiencing pseudo-hypoglycemia (also known as relative hypoglycemia, false hypoglycemia, or false low). When your blood sugar is tested, it is at least 4.0 mmol/L.

Background of Pseudohypoglycemia:

Pseudohypoglycemia is a condition in which the glucose level measured is not as high as the current level. It can be caused to in vitro glycolysis or compromised circulation. Clinical Patient 1: For alcohol poisoning, a 58-year-old male with a previous medical history of cell sickle features has been hospitalized. Fingerstick point-of-care tests have indicated low blood glucose (POCT). Glucose levels range from 17 to 60 mg/dL from fast and postprandial. The patient was asymptomatic, with no trembling, pulse, or sweating at all.

At a Glance:

Sometimes you obtain a low glucose test result that is merely meaningless. For example, the patient has no history of diabetes, no Pseudohypoglycemia agents, no hypoglycemic symptoms during the visit to the doctor. Symptoms may not accompany genuine hypoglycemia, but “pseudo hypoglycemia,” which does not represent the glucose concentration recorded in the blood at the time of the test was taken, can occur more commonly.

Reported hypoglycemia:

No laboratory measurement mistake should be confounded with Pseudohypoglycemia. Most laboratories hold samples for several days, so you should first arrange to repeat the test with the same sample. An actual measuring error happened when the outcome is different. In many circumstances, however, low glucose results will be validated, in which case the reported hypoglycemia reflects the genuine sample levels.

Role of Red Blood Cells:

Red blood cells (RBCs) can significantly metabolize glucose. At room temperature, as a result of this metabolism, the glucose concentration in a typical blood sample decreases by roughly 7 mg/dL/hour. So, when left at room temperature for four hours, a speed sample whose glucose level began at 80 mg/dL could be as concentrated as 52 mg/dL.

Pseudohypoglycemia as the source of white blood cells:

In people with polycythemia, the rate of metabolism is naturally higher. Sometimes, Pseudohypoglycemia may be the source of high numbers of white blood cells (e.g. >100,000 cells/mm3), both benign and malignant. These are the results of the lab affected by any factors. Your patient, in particular, take medicines – OTC medicines or herbs – that could influence the lab results.

Inhibit this metabolism:

To inhibit this metabolism, at least three are possible:

  1. Centrifugation of serum/plasma from the RBC
  2. Keep the sample in the cooler until analysis (or centrifugation)
  3. Sample collection in a specific rope containing a chemical that hinders glycolysis (e.g. sodium fluoride).

Test of Pseudohypoglycemia:

If centrifugation is not relatively early after the collection of the material, glycolysis is reported. In addition, no one can be sure of how long a delay has taken place. Likewise, if cooling is delayed or is not continuous, there will be glycolysis, and there will be no method of showing how long the sample was not at a cooling temperature.

Comparison of Patients:

Patient 1’s aetiology was probably linked to peripheral vascular diseases. In inpatient 2, a congestive heart defect, and inadequate peripheral perfusion were probable causes. So, the management of heart failure has been improved. The heating of the hands has improved peripheral circulation to a capillary recharge of < 2 seconds and cyanosis resolution that matches the level of POCT finger sticks to the level of venous blood.

Condition of patients in Pseudohypoglycemia:

The patients were alert and unconscious. Bilateral acrocyanosis, poor capillary refill output perimeter of > 5 seconds, pedal oedema, high JVP, and chest auscultation crackling were examined. Labs indicated BNP 1130 pg/mL (n<100 pg/mL), and echocardiogram echocardiography echoed around 35 per cent.

Peripheral pulses rate:

Peripheral pulses are regular. The results of the laboratory showed macrocytic anaemia, typically the metabolic panel. There were negative antibodies to antisocial-70, anticentromere, and ANA. Patient 2: A 91-year-old woman was discovered and admitted to POCT fingerstick with rapid glucose levels ranging from 30-50 mg/dL for decompensated heart failure. POCT finger sticks Postprandial glucose ranged from 55 to 120 mg/dL. The values of venous glucose ranged from 90 to 180 mg/dL.

Medication for Pseudohypoglycemia:

Glucose samples obtained in a fluoride tube are virtually always precise. In addition to standard PO2, PCO2, and pH parameters like electrolytes, free calcium, glucose, Lactate, modern blood gas analyzers may be utilized to measure. For these determinations, the advantage of such devices is very rapid turnaround times because the analysis is carried out on whole blood and not serum or plasma. Moreover, the analysis usually takes place at 37°C.

The glucose level in Pseudohypoglycemia:

In patients with Pseudohypoglycemia or high white blood cell counts (WBCs), an unexpected phenomenon may develop whose samples will be submitted to blood gas tools for study. Glucose levels will decline continuously over a period. As a result, glucose levels will be reduced. The devices often generate an error message as a stable endpoint is designed to wait. In those circumstances, the actual concentration of glucose is the first concentration shown at the start of the assay.

Prevent in vitro glucose metabolism:

In rare circumstances, fluoride inhibition does not work well in cases of Pseudohypoglycemia that are secondary to aberrant WBCs. In these instances, the sample must always be cold and centrifuged to prevent in vitro glucose metabolism. Therefore, every time a low finger club level shows normal glucose levels ranging from 85 to 115 mg/dL was observed, glucose POCT was repeated from the earlobe and validated with blood glucose measures from the venous stream. When examined, the patient showed modest cutaneous thickening of his hand without acrocyanosis.

Clinical lesson:

In clinical practice, low levels of glucose are often found. Therefore, it is important to determine whether or not non-diabetes is symptomatic. In asymptomatic individuals who do not fulfil the Whipple Triad before starting a thorough hypoglycemia process, it is recommended to test the glucose levels from different places.


At the time of low POCT glucose, both patients were asymptomatic and did not fulfil the trio (measured hypoglycemia, symptomatic, a reversal of symptoms on glucose administration). In addition, no diabetes or hypoglycemic agents had been reported to them. Therefore, normal levels of venous blood glucose recorded in low POCT glucose lead to Pseudohypoglycemia diagnosis.
