Significance of Negative control
Negative control refers to a group in experimental research that does not receive the treatment under investigation, serving as a benchmark for comparison with treated groups. This control is utilized to ensure that the experimental results are due to the treatment and not external factors. Additionally, negative controls help validate the accuracy of tests by confirming the absence of the target substance, ensuring no false positives. Thus, negative control is critical for robust scientific experimentation and result interpretation.

Hindu concept of 'Negative control'
In Hinduism, Negative control serves as a baseline for comparison in experiments, illustrated by 5% DMSO, which demonstrates no antibacterial effect, allowing researchers to assess the effectiveness of treatments like Pruthvisar Tailam against infections.
(1) This is a group in an experiment that does not receive the treatment, used as a baseline to compare the effects of the treatment.[1] (2) Dimethyl sulfoxide (DMSO), used as a solvent to reconstitute the test sample, used to assess its activity, if any, as a control in the study.[2] (3) This refers to a group of animals that did not receive the treatment being tested, used for comparison, and in this study it is used to assess the drug's effects.[3] (4) Negative control, represented by DMSO, was used in the antimicrobial study to compare the effectiveness of Pruthvisar Tailam, as described in the text.[4] (5) Five percent DMSO (negative control) did not show any ZOI for individual bacterial strains when studying antibacterial activity.[5]
The concept of Negative control in scientific sources
Negative control involves a group not receiving the experimental treatment to establish a baseline and ensure the experiment functions correctly by providing expected negative results for comparison against treated subjects.
(1) This is a control used to determine if a serum sample is positive, when the OD value is two-fold higher than the negative control, as stated in the text.[6] (2) This is a probe prepared from pUC18 plasmid DNA, used to ensure the specificity and reliability of the in situ hybridization results.[7] (3) A negative control, like 1× PBS, is a substance that is not expected to produce an effect and is used as a baseline for comparison in the experiments.[8] (4) A group of non-HD individuals whose PBMCs were used as a negative control in the experiment.[9] (5) These are experimental samples that are expected to show a negative result, used to ensure the test method is not giving false positives.[10]
