Overview of Glucose - Postprandial Blood

What is Glucose - Postprandial Blood?

The Blood Glucose Postprandial (PP) Test is performed to measure glucose levels in the blood after a period of 2 hours from the start of last meal to screen for Prediabetes and Diabetes Types 1 and 2. The word ‘Postprandial’ means after eating a meal.

Sample Type

The sample type collected for Glucose - Postprandial Blood is: Blood

Preparation for Glucose - Postprandial Blood

  • Blood sample is to be given 2 hours after the start of the meal.

Why Get Tested for Glucose - Postprandial Blood?

The Blood Glucose Postprandial (PP) Blood Glucose Test is performed:

·         To Screen for high blood sugar in presence of risk factors of Diabetes

·         To monitor treatment efficacy in patients undergoing treatment for Diabetes

·         As a part of a routine preventive health checkup

Understand more about Glucose - Postprandial Blood

Glucose is a simple sugar or monosaccharide which is the main source of energy for all the cells of the body, and the only energy source for the nervous system. Carbohydrates consumed in the diet are broken down in the body to their simplest form- glucose, which is absorbed by the intestines and transported by the blood to various organs. Glucose is subsequently utilized by cells of these organs to produce energy wherever necessary, and the excess is stored either as glycogen in the liver for short-term storage or in fat tissues as triglycerides for long-term storage. The uptake, utilization, and storage of glucose after it is absorbed in the intestines are facilitated by the hormone- insulin secreted by the pancreas. Insulin influences the transport of glucose to the organs requiring it, like the heart, brain, working muscles, etc. It also directs storage of excess glucose. The action of insulin reduces sugar levels in the blood.

After a meal, sugar levels increase in blood and insulin is secreted in response to reduce sugar levels until it becomes normal. If glucose levels fall too low in blood, another pancreatic hormone called glucagon is released, which directs the liver to convert stored glycogen into glucose and release it into the blood. The insulin and glucagon hormones create a feedback mechanism to keep blood glucose levels within the normal range. Imbalance in their activity causes high or low blood sugar levels in the blood.

The Blood Glucose Postprandial (PP) Test measures the glucose levels in the blood after a period of 2 hours from the start of last meal. The Blood Glucose PP test is usually done along with a Fasting Blood Glucose test.

This helps to determine if the body is able to utilize or store glucose efficiently. Excess sugar in blood indicates it is not being utilized or stored. This is principally caused due to Diabetes which can be of two types Type 1 or Type 2. Type 1 Diabetes is caused when insulin is not produced or produced in very little quantity. Type 2 Diabetes is caused when insulin produced is not utilized effectively by the body (Insulin resistance) and also due to decreased insulin production. In both these cases, blood sugar level rises, while cells are deprived of nutrition.



What Results of Glucose - Postprandial Blood mean?

Interpretations

  • Normal: under 140 mg/dl (7.8 mmol/l)

  • Impaired glucose tolerance or Pre-diabetes: between 140 and 200 mg/dl (7.8 and 11.1 mmol/l)

  • Diabetes: equal to or above 200 mg/dl (11.1 mmol/l)

Oral glucose tolerance test is usually recommended when the blood glucose levels fall between 140 and 200 mg/dl.


Patient Concerns about Glucose - Postprandial Blood

Frequently Asked Questions about Glucose - Postprandial Blood

Q. How is this test performed?
This test is performed on a blood sample. A syringe with a fine needle attached is used to withdraw blood sample from a blood vessel in your arm generally from the inner side of the elbow area. The doctor, nurse or the phlebotomist will tie an elastic band around your arm which will help the blood vessels to swell with blood and hence makes it easier to withdraw blood. You may be asked to tightly clench your fist. Once the veins are clearly visible, the area is cleaned with an antiseptic solution and then the needle is inserted into the blood vessel to collect the sample. You may feel a tiny pinprick during the procedure. Blood sample once collected is then sent to the laboratory.
Q. Is there any risk associated with this test?
There is no risk associated with the test. However, as this test involves a needle prick to withdraw the blood sample, rarely, a patient may experience increased bleeding, hematoma (blood collection under the skin) formation, bruising or infection at the site of needle prick.

MDRC is the pioneer in the field of imaging and pathology in the city. At a time when the healthcare of Gurgaon was in its infancy, MDRC started its operations from the New Railway Road in the year 1985. The journey which started with an X-Ray machine has reached a stage where MDRC today is in top league in terms of the range and quality of diagnostic facilities with more then 2500 tests done in house. There are two independent fully equipped centres located across the highway at New Railway Road in main city and one in Sector - 44 near HUDA city centre. Both the centres are spacious and have complete range of diagnostic facilities in fields of radiology, cardiology, pathology and general health. The experience and patient loyalty gained over the last 30 years has made us the number one diagnostic facility in the state of Haryana and NCR. It is because of our dedicated Doctors and high end equipments which help us solve the diagnostic dilemma in complicated cases that we get patients from all over Haryana and the NCR region as well as international patients. Our doctors bring with them highest level of knowledge and experience in their respective fields. The paramedical staff is highly qualified, well trained and motivated to deliver the best experience to our patients. The other support staff is caring and passionate about their work in order to achieve complete patient satisfaction. Modern diagnostics has expanded its facilities by running the diagnostic services at many other hospitals in the city. The footprint is expanding and now we have crossed national boundaries and have facility in Nepal and will soon extended our facility in more countries.
